Step-by-step explanation:

The number is 2 if five times the difference between a number and three is negative five the answer is 2.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is:

Five times the difference between a number and three is negative five. Find the number.

Let's suppose the number is x

From the question:

5(x - 3) = -5

After using the distributive property:

5x - 15 = -5

Add 15 on both sides:

5x - 15 + 15 = 10 + 15

5x = 25

Divide by 5 into both sides

x =25/5

x = 2

Thus, the number is 2 if five times the difference between a number and three is negative five the answer is 2.

Answer:

YOUR WRONG 27 IS NOT 45%

Step-by-step explanation:

[tex]\frac{27}{100}[/tex]=27%

100%=1 whole

Answer:

It is 60

Step-by-step explanation:

A better way to rephrase the problem is:

"what is 100 percent of something if 27 is 45% of something. ?"

so

100% * X  = ?

given:   27 = 45% * X

Solve for X,

27/ 45% = X

X = 27 / 0.45 = 60

so.  100% * X = 100% * 60 = 1 * 60 = 60

Answer:

x = 3

Step-by-step explanation:

The solution to the equation is x = (-1 + √(57))/2.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Using the logarithmic identity log(a) + log(b) = log(ab), we can simplify the left side of the equation:

log(x - 1) + log(x + 2) = log((x - 1)(x + 2))

So the equation becomes:

log((x - 1)(x + 2)) = log 12

Using the logarithmic identity log(a) = b is equivalent to a = 10^b, we can rewrite the equation as:

(x - 1)(x + 2) = 12

Expanding the left side and simplifying, we get:

x² + x - 14 = 0

Using the quadratic formula, we find:

x = (-1 ± √(1 + 4 x 14))/2

x = (-1 ± √(57))/2

Since we can't take the logarithm of a negative number, we discard the negative solution and obtain:

x = (-1 + √(57))/2

Therefore,

The solution to the equation is x = (-1 + √(57))/2.

I had the same problem too for math today so might as well help ya!

Answer:

To transform from polar coordinates  into Cartesian coordinates  we have:

x = r x cos(theta)

y = r x sin(theta)

r^2 = x^2 + y^2

=>   r = 2*cos(theta)

<=> r = 2*(x/r)

<=> 2x = r^2

<=> 2x  = x^2 + y^2

Hope this helps!

Final answer:

The expression 4/9 x 2/3 simplifies to 8/27, which cannot be reduced further as there are no common factors between the numerator and the denominator.

Explanation:

The original expression given is 4/9 x 2/3. To simplify this expression, we multiply the numerators together (4 x 2) and the denominators together (9 x 3). The product of the numerators is 8, and the product of the denominators is 27, giving us the fraction 8/27. This expression can't be simplified further because 8 and 27 have no common factors other than 1.

If we refer to the example of the scale factor, such as 1:4 scale, it is different from the multiplication of fractions. However, in the case of the proportion 1:2 = 4:x, we solve for x by cross-multiplying, resulting in x being 8. This is a proportional relationship and not directly related to the original fraction multiplication.

The product of the given expressions A, B, C, and D is 1. This is computed by recognizing A and C as conjugates (and likewise B and D), and using the difference of squares rule.

Given the expressions of A, B, C, D as written in the question, what needs to be done is to multiply these expressions together. Since B is the negative of A, and D is the negative of C, you can rewrite ABCD as:

A*(-A)*C*(-C)

which simplifies to -(AC)2. You'll notice that A and C are conjugates. This means that squaring them results in the difference of squares, or a2 - b2. Implementing this, we get:  

the product ABCD, we can use the distributive property of multiplication over addition. We have:

ABCD = (A + B)(C + D)

Substituting the given values of A, B, C, and D, we get:

ABCD = ((√2008 + √2009) + (-√2008 - √2009))((√2008 - √2009) + (√2009 - √2008))

-(sqrt{2008}2 - sqrt{2009}2) = -(2008 - 2009) = 1

Given that A = (√{2008}+√{2009}), B = (-√{2008}-√{2009}), C = (√{2008}-√{2009}), and D = (√{2009}-√{2008}), to find ABCD, we multiply the given values together:

ABCD = ((√{2008}+√{2009})(-√{2008}-√{2009}))((√{2008}-√{2009})(√{2009}-√{2008}))

By expanding the multiplication and simplifying the expressions, we get:

Step-by-step explanation:

Given,

Keesha bought = x binder.

Let Keesha bought (11-x) notebook.

Total money spent = $45

Cost of each binder = $ 6

Cost of each notebook = $ 2.50

Now,

Equation

$ 6 × x + $ 2.50 × (11-x) = $ 45

$ 6 x + $27.5 - $ 2.50 x= $ 45

$ 3.50 x = $ 17.5

x = 5

Number of binder = 5.

Number of cover = 11-5 = 6.

Final answer:

The two equations to determine the number of binders (b) and notebooks (n) Keesha purchased are: b + n = 11 and 6b + 2.50n = 45. These equations are based on the total number of items and the total cost of the items.

Explanation:

To determine the number of binders and notebooks Keesha purchased, we need to set up two equations based on the given information. The first equation will represent the total number of items purchased, and the second will represent the total cost of those items.

Equation 1 (total number of items):
b + n = 11

Equation 2 (total cost):
$6 × b + $2.50 × n = $45

In the above equations, b represents the number of binders and n represents the number of notebooks. These two equations can be used to solve for the variables b and n using methods such as substitution or elimination.

Answer:

0.0853

Step-by-step explanation:

Step 1

The first step would be to find the Z score

Formula for Z score is given as

z = x – μ /( σ ÷ √n)

Where

x = observed value

μ = mean

σ = Standard deviation

n = sample size

In the question we were given the above values as :

x = observed value = $7500

μ = mean = $7200

σ = Standard deviation = $1200

n = samples size = 30

Z score (z) = $7500 – $7200 /($1200÷ √30)

Z score = $300/ ( $1200 ÷ √30)

Z score = 1.3693063938

Approximately, the Z score = 1.37

Step 2

Using this formula:

1 - P(z > 1.37)

Using the Standard distribution table,

P(z > 1.37) is given as

0.9146565

Therefore,

1 - P(z > 1.37)

= 1 - 0.9146565

= 0.0853435

In the question we were asked to round it up to 4 decimal places

= 0.0853

Therefore, the probability that the mean daily revenue for the next 30 days will exceed​ $7000 is 0.0853.

Step-by-step explanation:

When we say the price of an object is marked down, it means the price of the object was reduced or decreased from the initial or original price.

In the above question:

The original price of a computer game = $45

The price is marked down or decreased by $18

We are asked to find the percent of the original price that is marked down.

This is calculated as:

(The price that the original price is marked down by ÷ Original price ) × 100

= ($18 ÷ $45) × 100

= 40%

Therefore, the percent of the original price that is marked down is 40%.

For example, Say the question was: How many times have you watched star wars this past month? It may not be the same question but it has the same format. So, if you ask someone how many times have they had watched Star Wars this past month, they will say a specific number, like 7. The same goes with question D.

Step-by-step explanation:

2/3 = 8/12

8/12 ÷ 1/12 = 8

This should be right. Sorry if it isn't.

Answer:

8 bowls

Step-by-step explanation:

In total, we have 2/3 of a gallon of ice cream. Essentially, we want to divide this 2/3 gallons into b bowls such that each bowl has 1/12 of a gallon.

We can write this as the mathematical equation:

2/3 ÷ b = 1/12

Multiply both sides by b:

2/3 = (1/12) * b

Divide both sides by 1/12:

(2/3) ÷ (1/12) = b

Remember that when dividing fractions, it's the same as multiplying by the reciprocal, so:

(2/3) ÷ (1/12) = b

(2/3) * (12/1) = b

b = 8

Thus, the answer is 8 bowls.
