Step-by-step explanation:

Solve:

8(a + 30)=80

Use the distributive property.

8a = -160

Divide both sides by 8.

a = -20

Your final answer would be a = -20

hope this ! (:   mark me as brainliest if you can

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
