I'm really not sure about the top and bottom answer but I know i can help you with 10. Anyways, to figure this out you just need to know how many minutes are in 5/6 of an hour than multiply that many minutes by 5, I think i'll let you figure this out. :)
(Answer is 250 minutes if you don't want to figure it out)
Answer:
E. 16y
Step-by-step explanation:
Given equation:
5(x - 6y) = 50y
Expand the brackets using<u>
Distributive Property for subtraction:</u> a(b - c) = ab - ac
⇒ 5 · x - 5 · 6y = 50y
⇒ 5x - 30y = 50y
Add 30y to both sides:
⇒ 5x - 30y + 30y = 50y + 30y
⇒ 5x = 80y
Divide both sides by 5:
⇒ 5x ÷ 5 = 80y ÷ 5
⇒ x = 16y
