If 7 ounces of cola costs $.59. How much should 19 ounces costs?

Answer:

130

Step-by-step explanation:

40 percent of what number is 52?

let this number be x

so, the equation is

40/100 x X= 52

divide 40/100 from both sides

X=52÷40/100

When you divide by a fraction, you multiply by its reciprocal

X=52 x 100/40

X=5200/40

X=130

40 percent of 130 is 52.

The value of the unknown number is 130.

Option A.

Given the parameter:

"40% of what number is 52"

Let's represent the unknown number as "x."

To determine the number for which 40% is equal to 52, we can set up an equation and solve for the unknown number.

Hence:

40% of the number = 52

40% of x = 52

40% × x = 52

Convert the percentage to a decimal.

40% = 40/100 = 0.40

Now, rewrite the equation as:

0.40 × x = 52

0.4x = 52

To solve for the value of "x," divide both sides of the equation by 0.40:

x = 52/0.4

x = 130.

Therefore, 40 percent of 130 is 52.

Option A) 130 is the correct answer.

Answer:

Given the expression -3 - 4(2x- 3) the correct solution is -8x + 9.

Step-by-step explanation:

Andy wrote -14x + 21, so his error was to do de substraction (-3 -4) and then distribute -7(2x-3) = -14x+ 21.

Sylvie wrote -8x -6. Her error was to multiplied -4 only for 2x,

then -3 - 4(2x -3) = -3 -8x -3 = -8x -6.

Andy incorrectly distributed the negative sign and Sylvie made an error in simplifying the expression. The correct answer is -8x + 9.

Andy's error: He incorrectly distributed the negative sign to both terms inside the parentheses. When distributing a negative sign to each term, the sign of each term should change. So, -4(2x - 3) becomes -8x + 12. However, Andy erroneously distributed the negative sign to only the first term, resulting in -14x + 21.

Sylvie's error: She incorrectly simplified the expression -8 - 6, which is equal to -14. However, this is not the correct result for the entire expression -3 - 4(2x - 3).

The correct answer is obtained by applying the distributive property and combining like terms. First, simplify the expression inside the parentheses: -4(2x - 3) = -8x + 12. Then, combine the terms outside the parentheses with the simplified expression: -3 - 8x + 12 = -8x + 9.

Answer:

$22.20

Step-by-step explanation:

We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.

Let's set up our equation by making 13.32 into a fraction.

13.32/x

We will represent the present's actual cost with the letter x.

13.32/x = 3/5

We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a fraction of the present's cost, not the whole cost.

We solve this by doing cross multiplication. Multiply the 13.32 by the 5.

13.32 x 5 = 66.6

Next we divide 66.6 by 3 to get 22.2

66.6/3 = 22.2

This gives us our final answer of $22.20. This means that the cost of the original present was $22.20

The question involves setting up a proportion to find the total cost of the present. This was done step-by-step by dividing $13.32 by 3 to find 1/5 of the cost, and then multiplying by 5 to find the full cost. The present cost approximately $22.20

The subject of your question is mathematics, particularly a topic in proportion. The information given is that $13.32 represents 3/5 of the cost of the present. We could set up a proportion to help calculate the full cost. If 3/5 is equal to $13.32, then 1 (or 5/5) would be equal to the full price of the present. We can solve for the full price by dividing $13.32 by 3 and then multiplying by 5 (since 5/5 represents the whole or full cost).

Final answer:

Tonka can load a maximum of 29 boxes on the elevator.

Explanation:

To calculate the number of boxes Tonka can load on the elevator, we need to divide the maximum weight capacity of the elevator by the weight of each box. The weight capacity of the elevator is 2000 lb, and each box weighs 67 lb. Therefore, the number of boxes Tonka can load is found by dividing 2000 lb by 67 lb:

Number of boxes = 2000 lb ÷ 67 lb = 29.85

Since we can't have a fraction of a box, Tonka can load a maximum of 29 boxes on the elevator.

We can express 5 × 23 as

5(20 + 3) ← distribute terms in parenthesis by 5

= 5 × 20 + 5 × 3

= 100 + 15

= 115

By distributive property , the number 5 x 23 = 115

What is Distributive Property?

The distributive property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend individually by the number and adding the products together.

For a product of two numbers , a and d , d = b + c

By distributive property ,

a x ( b + c ) = a x b + a x c

Given data ,

Let the number be 5 x 23

Now , the number 23 can be split into ( 20 + 3 )

By opening the parentheses ,

5 x ( 20 + 3 )

The number 5 is first multiplied by 20 and then multiplied by 3 , and the sum of both the products will be taken

So ,

5 x 23 = 5 ( 20 + 3 )

5 x 23 = 5 ( 20 ) + 5 ( 3 )

5 x 23 = 100 + 15

5 x 23 = 115

Hence , by distributive property the product 5 x 23 is 115

The statement 2 + (3 + 4) = 2 + (4 + 3) is the one that uses the commutative property of addition, which states that changing the order of numbers being added does not affect the sum. So correct answer is first option.

The statement that uses the commutative property of addition is 2 + (3 + 4) = 2 + (4 + 3). The commutative property of addition states that the order in which two numbers are added does not change the sum.

This is represented by the equation A+B=B+A. In our specific example, changing the order of 3 and 4 does not affect the sum when added to 2.

This demonstrates the commutative property in a clear manner.

Answer:

y = 3x² + 54x + 240

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (- 9, - 3), thus

y = a(x + 9)² - 3

To find a substitute either of the roots into the equation

Using (- 8, 0), then

0 = a(- 8 + 9)² - 3

0 = a - 3 ( add 3 to both sides )

a = 3

y = 3(x + 9)² - 3 ← in vertex form

Expand factor and simplify

y = 3(x² + 18x + 81) - 3

  = 3x² + 54x + 243 - 3

  = 3x² + 54x + 240 ← in standard form

The answer is D. 12x - 3.

Step-by-step explanation:

To add these functions, we just add the terms.

f(x) + g(x) = (7x - 4) + (5x + 1)

7x - 4 + 5x + 1 | Simplify

7x + 5x - 3

12x - 3.

Answer:

Option D. (12x - 3)

Step-by-step explanation:

Madden's total cups of coffee made is represented by the function f(x).

f(x) = 7x - 4

Jenn's total cups of coffee made is represented by the function g(x).

g(x) = 5x + 1

Now we have to write a function that represents the total cup of coffee that represents they made.

That will be represented by f(x) + g(x) = (7x - 4) + (5x + 1)

f(x) + g(x) = 12x - 3

Therefore, option D. will be the answer.

The equivalent value for (s \\circ f) (-7), given s(x) = 2 - x and f(x) = 3x, is 23.

The question asks which value is equivalent to (s \\circ f) (-7), where s(x) = 2 - x and f(x) = 3x.

To solve for (s \\circ f) (-7), we first need to find f(-7). Since f(x) = 3x, we substitute x with -7:
f(-7) = 3(-7) = -21.
Next, we calculate s(f(-7)), which means we substitute x in s(x) with the value of f(-7):
s(-21) = 2 - (-21) = 2 + 21 = 23.

Therefore, the equivalent value  is 23.

Azeneth needs to buy 4x² + 2x + 24 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- Azeneth is putting a fence around her rectangular garden

- The width of the garden is 4x + 5 feet

- The  length is 2x² – 3x + 7 feet

- We need to find how much total fencing  Azeneth needs to buy in

  terms of x

∵ The fence will put around the four sides of the rectangular garden

∴ The length of the fence is equal to the perimeter of the garden

- The perimeter of any rectangle = 2l + 2w, where l and w are its

  dimensions

∵ The perimeter of the garden = 2 × its width + 2 × its length

∵ Width = 4x + 5

∴ 2 × width = 2(4x + 5) = 8x + 10

∵ Length = 2x² - 3x + 7

∴ 2 × length = 2(2x² - 3x + 7) = 4x² - 6x + 14

∴ The perimeter of the garden = 8x + 10 + 4x² - 6x + 14

- Add like terms

∴ The perimeter of the garden = 4x² + (8x - 6x) + (10 + 14)

∴ The perimeter of the garden = 4x² + 2x + 24

∵ The length of the fence = the perimeter of the garden

∴ The length of the fence = 4x² + 2x + 24 feet

* Azeneth needs to buy 4x² + 2x + 24 feet

Answer: 51.1 units squared

Step-by-step explanation: the area of each face is 306.6 so then you would divided that by 6 since there are 6 sides in a cube so you get 51.1 and if multiplied by 6 it equals 306.6

The area of each face of a cube 306.6 is 51.1 square units.

A solid three-dimensional shape called a cube contains six square faces, eight vertices, and twelve edges.

A cube has 6 faces.

So the area of each face is (side x side).

So total area is equal to 6 times the area of each side.

Area = 6 x (side x side)

Now, substitute in your numbers and solve for the side length

306.6 = 6 (side)²

so first divide both sides by 6,

we get,

Answer:

The solution is (2 , -1)

Step-by-step explanation:

* You have two ways to solve the system of equations

1. Elimination method:

By making the coefficients of one of the two variables equal in the 2

equations in magnitude and different in sign to eliminate it and find the

other variable

2. Substitution method:

By finding one of the two variables in terms of the other in one of the

two equations and substitute this value in the second equation

* Lets solve our system using the elimination method

∵ 6x + 7y = 5 ⇒ (1)

∵ 2x - 3y = 7 ⇒ (2)

- Multiply equation (2) by -3 to eliminate x

∵ (-3)(2x) - (-3)(3y) = (-3)(7)

∴ -6x + 9y = -21 ⇒ (3)

- Add equation (1) and (3)

∴ 7y + 9y = 5 + -21

∴ 16y = -16

- Divide each side by 16

∴ y = -1

- Substitute the value of y in equation (1)

∴ 6x + 7(-1) = 5

∴ 6x - 7 = 5

- Add 7 to both sides

∴ 6x = 12

- Divide both sides by 6

∴ x = 2

* The solution is (2 , -1)
