At a sale, Salazar bought 4 T-shirts and 3 pairs of jeans for $181. At the same store, Jenna bought 1 T-shirt and 2 pairs of jeans for $94. The T-shirts were all the same price, and the jeans were all the same price. Write a system of equations that can be used to represent this situation

Answer:

The four consecutive even integers are 4, 6, 8 and 10.

Step-by-step explanation:

Let the four consecutive even integers be [tex]x, x+2, x+4, x+6[/tex]

It is provided that the sum of these consecutive even integers is 28.

Solve for x as follows:

[tex]x+ x+2+ x+4+ x+6=28\\4x+12=28\\4x=16\\x=4[/tex]

The four consecutive even integers are:

[tex]x=4\\x+2=4+2=6\\x+4 = 4 +4 =8\\x+6=4+6=10[/tex]

Thus, the four consecutive even integers are 4, 6, 8 and 10.

Step-by-step explanation:

[tex](+)(+)=(-)(-)=(+)\\(+)(-)=(-)(+)=(-)\\\\-(-x-3)=-1(-x-3)\qquad\text{use the distributive property}\\\\=(-1)(-x)+(-1)(-3)=x+3[/tex]

Answer:

Jackie is incorrect.

Step-by-step explanation:

[tex]\frac{3}{4}[/tex] [tex]\left {x2} \atop {x2}} \right.[/tex] = [tex]\frac{6}{8}[/tex]

[tex]\frac{3}{4}[/tex] is equivalent to [tex]\frac{6}{8}[/tex] not [tex]\frac{7}{8}[/tex]

Jackie is mistaken when she claims that the fraction 7/8 is equal to 3/4. We compare the numerator (the top number) and denominator (the bottom number) of two fractions to see if they are equal.

In this instance, 3/4 has a denominator of 3 and a numerator of 4, whereas 7/8 has a numerator of 7 and a denominator of 8, respectively. The fractions cannot be equal since the numerators and denominators vary.

Two fractions must have the same numerator to denominator ratio in order for them to be equal. In this situation, 7/8 is a bigger fraction than 3/4. Jackie's assertion that 7/8 is comparable to 3/4 is therefore false.

Explanation:

The given information can be summarized in this way:

Following Newton's second law, net force equal mass times acceleration:

To predict the motion, you apply Newton's second law in each direction (vertical and horizontal)

        Net vertical force = 8N - 8N = 0. This means there is not motion in the vertical direction.

         Net horizontal force = 6N - 4N = 2N. This means there is a net force of 2N to the right, which lets you predict that the bone starts to accelerate to the right; this is, the bone begins to move toward the right.      

Answer:

A. It begins to move toward the right.

Answer:

The two numbers are 15 and 6.

Step-by-step explanation:

Given:

The difference between two numbers is 9.

The first number plus twice the other number is 27.

Now, to find the two numbers.

Let the first number be [tex]x.[/tex]

And the other number be [tex]y.[/tex]

So, the difference between two numbers is 9.

[tex]x-y=9[/tex]

[tex]x=9+y[/tex]    ............(1)

As, given the first number plus twice the other number is 27.

According to question:

[tex]x+2y=27[/tex]

Substituting the value of [tex]x[/tex] from equation (1):

[tex](9+y)+2y=27\\9+y+2y=27\\9+3y=27[/tex]

Subtracting both sides by 9 we get:

[tex]3y=18[/tex]

Dividing both sides by 3 we get:

[tex]y=6.[/tex]

The other number = 6.

Now, substituting the value of [tex]y[/tex] in equation (1):

[tex]x=9+y\\x=9+6\\x=15.[/tex]

The first number = 15.

Therefore, the two numbers are 15 and 6.

For radius x, Choice 'A' π/4 is the correct answer.

For radius 10x, Choice 'B' π/4 is the correct answer.

For radius 100x, Choice 'B' π/4 is the correct answer.

Step-by-step explanation:

The Area of the circle = πr^2, where "r" is the length of the radius.

The Area of square = a^2, where "a" is the length of an edge of a square.

CASE 1 :

Substitute radius r = x and edge length a = 2x,

Area of circle = π*x*x = πx^2

Area of square = 2x*2x = 4x^2

The ratio of the area of the circle to the area of square = πx^2 / 4x^2 = π/4

Choice 'A' π/4 is the correct answer.

CASE 2 :

Substitute radius r = 10x and edge length a = 20x,

Area of circle = π*10x*10x = 100πx^2

Area of square = 20x*20x = 400x^2

Ratio of the area of the circle to the area of square = 100πx^2 / 400x^2

                                                                                         = π/4

Choice 'B' π/4 is the correct answer.

CASE 3 :

Substitute radius r = 100x and edge length a = 200x,

Area of circle = π*100x*100x = 10000πx^2

Area of square = 200x*200x = 40000x^2

Ratio of area of the circle to the area of square = 10000πx^2 / 40000x^2

                                                                                  = π/4

Choice 'B' π/4 is the correct answer.

Answer: x = 42

Step-by-step explanation:

Step  1  :

           x

Simplify   —

           3

Equation at the end of step  1  :

 x    

 — -  14  = 0  

 3    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         14     14 • 3

   14 =  ——  =  ——————

         1        3    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (14 • 3)     x - 42

————————————  =  ——————

     3             3    

Equation at the end of step  2  :

 x - 42

 ——————  = 0  

   3    

Step  3  :

When a fraction equals zero :

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x-42

 ———— • 3 = 0 • 3

  3  

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x-42  = 0

Solving a Single Variable Equation :

3.2      Solve  :    x-42 = 0  

Add  42  to both sides of the equation :  

                     x = 42

Your answer: x = 42

Answer:

42

Step-by-step explanation:

x / 3 = 14.

The question required you to solve for x.

First, multiply both the LHS and the RHS by 3. The aim is to make x independent.

x/3 * 3 = 14 * 3

Therefore:

x = 42

2y=-4

y=-4/2=-2

-2-x=6

x=-2-6=-8

Answer:

x=-8, y=-2. (-8, -2).

Step-by-step explanation:

To answer the question, we evaluated two absolute value expressions individually by converting mixed numbers to improper fractions, performing the operations, and taking absolute values. The sum of these evaluations is 14.

The question involves evaluating two absolute value expressions and adding the results. We will work through each expression step by step.

First Expression

|6 3/8 - 2|

To solve this, convert the mixed number to an improper fraction, subtract 2, and then find the absolute value.

Convert 6 3/8 to an improper fraction: (6 × 8) + 3 = 51/8.

Subtract 2 (written as 16/8) from 51/8: 51/8 - 16/8 = 35/8.

The absolute value of 35/8 is 35/8, as it is already positive.

Second Expression

|-8 5/8 + (-1)|

Similar approach: convert to an improper fraction, add -1, and find the absolute value.

Convert -8 5/8 to an improper fraction: (-8 × 8) - 5 = -69/8.

Add -1 (written as -8/8) to -69/8: -69/8 - 8/8 = -77/8.

The absolute value of -77/8 is 77/8, as we discard the negative sign in absolute value operations.

Add the results of both expressions: 35/8 + 77/8 = 112/8 = 14.

Step-by-step explanation:

Answer:

part A:

M = 4(2x + 6)

   = 8x + 24

part B:

option 1) i think the x value is equal for both M and N since they have the value 8.

option 2)  If you meant to solve M and N with an EQUATION then here's your answer:

8x+24 = 8x+10

24≠10   (you subtract 8x when taken to the other side)

So, the answer would be NO SOLUTION

Final answer:

To apply the distributive property to expression M, multiply each term inside the parentheses by 4, resulting in M = 8x + 24. Comparing this to expression N, which is N = 8x + 10, one can see that M and N are not equivalent because their constant terms differ.

Explanation:

Part A: Equivalent Expression for M

To find an equivalent expression for M, we use the distributive property which states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. Therefore:

M = 4(2x + 6)

Apply the distributive property to get:

M = (4 × 2x) + (4 × 6)

M = 8x + 24

Part B: Are M and N Equivalent?

To determine if M and N are equivalent expressions, we must compare the expressions that we have for M and N:

M = 8x + 24

N = 8x + 10

Since the coefficients of x are the same but the constant terms are different, the two expressions are not equivalent for any value of x.

Answer:

n = [tex]\frac{1}{3}[/tex]

3(n+1) = 4

distributive property means multiply every term in the parentheses by the number on the left and add the new terms.

(3*n) + (3*1) = 4

3n + 3 = 4

     -3    -3         subtract 3 from both sides.

3n = 1

Answer:

y = 25

Step-by-step explanation:

Given that the quantities are proportional then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition y = 10 when x = 6

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{10}{6}[/tex] = [tex]\frac{5}{3}[/tex]

y = [tex]\frac{5}{3}[/tex] x ← equation of proportion

When x = 15, then
