What is the value of r in: 1/7(105+r)=20

stealth61 [152]

Use the distributive property.

1/7(105 + r) = 20
15 + (1/7)r = 20

Then subtract each side of the equation by 15.

15 + (1/7)r = 20
(1/7)r = 5

Divide both sides by 1/7.

(1/7)r = 5

r = 35

So, the answer to this question is r is equal to 35.

$\frac{6}{10x^2} \div \frac{6}{10x^3-60x^2} = \frac{6}{10x^2} \cdot \frac{10x^3-60x^2}{6} =\frac{1}{10x^2} \cdot \frac{10x^2(x-6)}{1} =x-6$
