Answer: x = 45

====================================

Work Shown

x/y = 10/4

x/18 = 10/4 ... replace y with 18

x*4 = 18*10 ... cross multiply

4x = 180

4x/4 = 180/4 ... divide both sides by 4

x = 45

Final answer:

By cross-multiplying the given proportion x/y=10/4 with y=18, we determine that the value of x is 45.

Explanation:

To find the value of x given that x/y=10/4 and y = 18, we can use the method of cross-multiplication. This method involves multiplying the numerator of one fraction by the denominator of the other fraction and setting the two products equal to each other. So, we set up the equation:

[tex]\(\frac{x}{y} = \frac{10}{4}\)[/tex]

Let's substitute y with 18:

[tex]\(\frac{x}{18} = \frac{10}{4}\)[/tex]

We then cross-multiply and solve for x:

[tex]4x = 10 \times 18[/tex]

4x = 180

[tex]x = \frac{180}{4}[/tex]

x = 45

Therefore, the value of x is 45 when y is 18.

Answer:

There is one solution

Step-by-step explanation:

You can tell by looking at it that 2x and 3x are different. Both are obtained once the brackets have been removed. So you will get just one answer.

2(x -1) = 3(x - 4)                  Remove the brackets.

2x - 2 = 3x - 12                  Subtract 2x from both sides.

2x - 2x - 2 = 3x - 2x - 12   Combine

-2 = x -12                           Add 12 to both sides.

-2 + 12 = x -12 +12             Combine

10 = x

The solutions to the equation 7x(x+1.8)=0 are x = 0 and x = -1.8.

The highest power of the polynomial function is defined as the degree.

The Fundamental Theorem of Algebra asserts that a polynomial has n roots if its degree is n.

The equation is 7x(x+1.8)=0.

To solve this equation, we can use the property that if the product of two factors is equal to zero, then at least one of the factors must be zero.

Therefore, we set each factor equal to zero and solve for x:

7x = 0

x = 0

x + 1.8 = 0

x = -1.8

So, the solutions to the equation 7x(x+1.8)=0 are x = 0 and x = -1.8.

To solve the equation 7x(x+1.8)=0, set each factor equal to zero to find the two possible solutions for x, which are 0 and -1.8.

To solve the equation 7x(x+1.8)=0, we need to set each factor equal to zero and solve for x.

Setting 7x=0, we find x=0. Setting x+1.8=0, we subtract 1.8 from both sides to get x=-1.8. Therefore, the solutions to the equation are x=0 and x=-1.8.

SEO Keywords: quadratic equation, solve, factor, solutionsThe given equation is 7x(x+1.8)=0. This is a quadratic equation that can be easily solved by setting each factor equal to zero. Here's how you can find the value(s) of x:

Therefore, the two possible values for x are 0 and -1.8.

Answer:

x = - 6 or x = 1

Step-by-step explanation:

given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0

then the equation can be solved using the quadratic formula

• x = ( - b ± [tex]\sqrt{b^2-4ac}[/tex]) / 2a

x² + 5x - 6 = 0 is in standard form

with a = 1, b = 5 and c = - 6

x = (- 5 ± [tex]\sqrt{5^2-(4(1)(-6)}[/tex]) / 2

  = (- 5 ± [tex]\sqrt{25+24}[/tex]) / 2

  = (- 5 ± [tex]\sqrt{49}[/tex]) / 2

x = [tex]\frac{-5-7}{2}[/tex] = [tex]\frac{-12}{2}[/tex] = - 6

or x = [tex]\frac{-5+7}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

The solutions to the quadratic equation x² + 5x - 6 = 0 are x = 1 and x = -6.

To solve the quadratic equation x² + 5x - 6 = 0, Nathaniel used the quadratic formula.

The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a), where a, b, and c correspond to the coefficients of the quadratic equation.

In this case, a = 1, b = 5, and c = -6.

Substituting these values into the quadratic formula, we get x = (-5 ± √(5² - 4(1)(-6))) / (2(1)).

Simplifying further, we have x = (-5 ± √(25 + 24)) / 2.

This yields two solutions: x = (-5 + √49) / 2 and x = (-5 - √49) / 2.

Simplifying the square root, we get x = (-5 + 7) / 2 and x = (-5 - 7) / 2.

Therefore, the solutions to the quadratic equation are x = 1 and x = -6.

Answer:

35 ants left

Step-by-step explanation:

Answer: choice A

f(x) = (1/4)x^2, f(x) = -0.5x^2, f(x) = x^2

=======================================================

The coefficient in front of the x^2 term tells us how wide or narrow the parabola will be. It turns out that the further the coefficient value is from 0, in either direction, this will make the parabola more narrow.

Notice how 1/4 = 0.25 which is less than |-0.5| = 0.5 meaning that f(x) = (1/4)x^2 is wider than f(x) = -0.5x^2

Then comparing f(x) = -0.5x^2 to f(x) = 1x^2, we see that 0.5 is smaller than 1, so f(x) = -0.5x^2 is wider than f(x) = 1x^2

That is why the order from widest to narrowest is f(x) = (1/4)x^2, f(x) = -0.5x^2, f(x) = x^2

A graph shown below helps confirm the answer (note the color coding). In figure 1 is the graph of all three functions together. In figure 2, I reflect the second function help show the comparison of why it's the middle-most in terms of how wide it is (it is the orange parabola, which is the reflection of the red parabola)

Answer:

[tex]\dfrac{1}{24}[/tex]

Step-by-step explanation:

1. The student is allowed to choose white, blue, green or black Polo shirts. So the student has 4 possibilities to select shirt and the probability of wearing the blue shirt is [tex]\dfrac{1}{4}.[/tex]

2. The student is allowed to choose khaki, black or plaid skirts/pants. So the student has 3 possibilities to select skirt and the probability of wearing the plaid skirt is [tex]\dfrac{1}{3}.[/tex]

3. The student is allowed to choose black or brown shoes. So the student has 2 possibilities to select shoes and the probability of wearing black shoes is [tex]\dfrac{1}{2}.[/tex]

Now use the product rule for probabilities:

[tex]Pr=\dfrac{1}{4}\cdot \dfrac{1}{3}\cdot \dfrac{1}{2}=\dfrac{1}{24}.[/tex]

Final answer:

To divide 65.2 by 26, you perform the division to find that 26 goes into 65.2 exactly 2.5 times. Therefore, the answer, when rounded to the nearest tenth, is 2.5.

Explanation:

To divide 65.2 by 26, start with the division process. Place a decimal point directly above the decimal point in the dividend within the answer area. Since 26 does not go into 6, but goes into 65 twice, write 2 above the 5 in the dividend. Multiply 2 by 26 to get 52, and subtract this from 65, which leaves a remainder of 13. Bring down the 2 from the dividend to get 132.

Now, divide 26 into 132, which goes exactly 5 times. Multiplying 5 by 26 gives 130, subtract this from 132 to get a remainder of 2. Because we are left with no more numbers to bring down and our remainder is less than 26, we stop. The answer to 65.2 divided by 26 when rounded to the nearest tenth is 2.5.

Answer:

The labor fee is $14.25, each quart of oil costs $2.25.

Step-by-step explanation:

Let $x be thee price of each quart of oil and $y be a flat fee for labor.

1. If the oil change for one car required 5 quarts of oil, then these 5 quarts cost $5x and together with a flat fee for labor it cost $25.50. Thus,

5x+y=25.50.

2. If the oil change for another car required 7 quarts of oil, then these 7 quarts cost $7x and together with a flat fee for labor it cost $30.00. Thus,

7x+y=30.00.

3. Subtract from the second equation the first one, then

[tex]7x+y-(5x+y)=30.00-25.50,\\ \\7x+y-5x-y=4.50,\\ \\2x=4.50,\\ \\x=\$2.25.[/tex]

Substitute it into the first equation:

[tex]5\cdot 2.25+y=25.50,\\ \\y=25.50-11.25,\\ \\y=\$14.25.[/tex]

The labor fee is $14.25, each quart of oil costs $2.25.

The labor fee is $14.25 and the cost per quart of oil is $2.25.

To find the labor fee and cost per quart of oil, we can set up a system of equations using the given information. Let x represent the cost of each quart of oil and y represent the labor fee.

We have the equations:

5x + y = 25.50
7x + y = 30.00

We can solve this system of equations using substitution or elimination. Substituting y from the first equation into the second equation, we get:

7x + (25.50 - 5x) = 30.00

2x = 4.50

x = 2.25

Substituting x back into the first equation, we get:

5(2.25) + y = 25.50

11.25 + y = 25.50

y = 14.25

Therefore, the labor fee is $14.25 and the cost per quart of oil is $2.25.

Answer:

3750 feet

Step-by-step explanation:

Given that Paulo begins at Stop 1 and then walks to Stop 2, then Stop 3, and then Stop 4. Then he walks to Stop 1 again.

Where stops are given by coordinates:

Stop 1 at (−2,1)

Stop 2 at (−2, −7) ​​

Stop 3 at (5,−7)

Stop 4 at (5, 1)

The path between each stop is a straight line. One unit on the coordinate grid equals 125 feet.

Now we need to find about what is the total distance Paulo walked.

So first we graph those points so that we can easily count the length of each side. then add each side to get the total length

length of rectangular path = 8+7+8+7=30

since one unit on the coordinate grid equals 125 feet. So to find the actual length we need to multiply 30 by 125 feet.

Hence final answer will be 125*30 = 3750 feet.
