Solve for r. You must write your answer in fully simplified form.<br> -20 = -15r

nevsk [136]

Answer:

r = 4/3

Step-by-step explanation:

-20 = -15r

Divide both sides by -15.

-20 / -15 = r

The negatives cancel, so

20 / 15 = r

Simplify by taking 5 out of the numerator and denominator. 20/5 = 4, 15/5 = 3.

4 / 3 = r

What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}?

tangare [24]

Answer:

{6,7,8,9,10}

Step-by-step explanation:

Solve the inequality using inverse operations.

$3r\leq 4r-6\\3r-4r\leq -6\\-r\leq -6\\r\geq 6$

This solution means values equal to or larger than 6 from the set are solutions. This means 6, 7, 8, 9, and 10 are the solution set.
