8 + 8( 8 - n ) = 40 + 8n
Ierofanga [76]

n=2

8+8(8-n)=40+8n (distribute 8 through the parenthesis)

8+64-8n=40-8n (add the numbers)

<em>72-</em>8n=40+8n (move the variable to the left side and change its sign)

<em>72</em><em>-</em>8n+8n=40

-8n+8n=40<em>-72</em> (connect like terms)

-16n = -32 (divide both sides by -16)

<u><em>n=2</em></u>

To make a specific hair dye, a hair stylist uses a ratio of 1 1/8 oz of red tone, 3/4 oz of gray
nadezda [96]

Answer:

We can call the amounts of red, gray, and brown dye 1 1/8x, 3/4x and 5/8 x respectively and we can write the equation:

1 1/8x + 3/4x + 5/8x = 20

2 1/2x = 20

x = 8 which means that the stylist needs 1 1/8 * 8 = 9 oz red, 3/4 * 8 = 6 oz gray and 5/8 * 8 = 5 oz brown.
