Answer 2

Answer:

x = 22

Step by step solution:

5x+(3x-18)+x=180

Simplifying

5x + (3x + -18) + x = 180

Reorder the terms:

5x + (-18 + 3x) + x = 180

Remove parenthesis around (-18 + 3x)

5x + -18 + 3x + x = 180

Reorder the terms:

-18 + 5x + 3x + x = 180

Combine like terms: 5x + 3x = 8x

-18 + 8x + x = 180

Combine like terms: 8x + x = 9x

-18 + 9x = 180

Solving

-18 + 9x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 9x = 180 + 18

Combine like terms: -18 + 18 = 0

0 + 9x = 180 + 18

9x = 180 + 18

Combine like terms: 180 + 18 = 198

9x = 198

Divide each side by '9'.

x = 22

if anya mixed 2/3 cups of white paint with 2 2/3 cups blue paint, how many cups of blue paint would she need for 3/4 cups of white paint?

Answers

You would add the 2/3 and the other 2/3 and then the 3/4 and then you would keep the 2 in the front of those numbers hope this helps

She needs 3/16 cups of blue paint for 3/4 cups of white paint.

Given that,

if Anya mixed 2/3 cups of white paint with 2 2/3 cups blue paint,

We have to determine,

How many cups of blue paint would she need for 3/4 cups of white paint.

According to the question,

if Anya mixed 2/3 cups of white paint with 2 2/3 cups blue paint,

Let, x cups of blue paint would she need for 3/4 cups of white paint.

To determine the value of x calculation must be done in a single unit by using the unitary method following all the steps given below.

Anya mixed 2/3 cups of white paint = 2 2/3  cups blue paint,

x cups of blue paint = 3/4 cups of white paint.

Therefore,

She needs x cups of blue paint is,

[tex]\dfrac{2}{3} = \dfrac{8}{3}\\\\x = \dfrac{3}{4}[/tex]

Solving the equation,

[tex]\dfrac{2}{3} \times \dfrac{1}{x} = \dfrac{8}{3}\times \dfrac{4}{3}\\\\ \dfrac{2}{3x} = \dfrac{32}{9}\\\\= 2 \times 9 = 3x \times 32\\\\= 18 = 96x\\\\x = \dfrac{18}{96}\\\\x = \dfrac{3}{16}[/tex]

Hence, She needs 3/16 cups of blue paint for 3/4 cups of white paint.
