x + y = 3.36 --> the boys are splitting $3.36

x = 3y - .12 --> one boy received $.12 less than 3 times as much as the other

--> substitute the second equation for the x in the first equation


(3y - .12) + y = 3.36 --> combine like terms

4y - .12 = 3.36 --> add .12 to both sides of the equation

4y = 3.48 --> divide both sides by 4

y = .87

the other boy gets $0.87

substitute into x = 3y - 12


x = 3(.87) - .12

x = 2.61 - .12

x = 2.49

the first boy gets $2.49

A recipe uses 2 cups of flour to make 18 cupcakes. How much flour is needed to make 27 cupcakes?
drek231 [11]

Answer:

3 cups

Step-by-step explanation:

we can solve this by setting up ratios

\frac{2 cups}{18 cupcakes} = \frac{x}{27 cupcakes}

cross multiply:

(2)(27) = 18x

54 = 18x

solve for x

x = 3 cups

How can you write the expression 7(b – 2) in words?
m_a_m_a [10]

Solution:

Let's verify each option to see which is correct.

<u>Option A</u>

Two subtracted from the quotient of seven divided by b.

  • => 7/b - 2 = 7(b - 2)                                                                [False]

<u>Option B</u>

Seven added to difference of b minus two.

  • => 7 + (b - 2) = 7(b - 2)                                                           [False]

<u>Option C</u>

The quotient of seven divided by b minus two.

  • => 7/b - 2 = 7(b - 2)                                                               [False]

<u>Option D</u>

Two subtracted from seven times b

  • => 7b - 2 = 7(b - 2)                                                                [False]

<u>Option E</u>

The product of seven and the difference of b minus two

  • => 7 x (b - 2) = 7(b - 2) = 7(b - 2)                                           [True]

Option E is correct.

The two legs of a right triangle are 20 and x - 8, and the hypotenuse is x. Find the length of the hypotenuse.
oksian1 [2.3K]
20^2 + (x-8)^2 = x^2

x^2 = 400 + x^2 -16x + 64

16x = 464

x = 29 = hypotenuse

Double - Check
29^2 = 20^2 + 21^2
841 = 400 + 441
