(1/2) / (1/4) = 1 / x......1/2 wall to 1/4 hr = 1 whole wall to x hrs
cross multiply
(1/2)(x) = (1/4)(1)
1/2x = 1/4
x = 1/4 * 2
x = 2/4 reduces to 1/2....so it will take 1/2 hr (or 30 minutes) to paint the whole wall.
The answer is 15
Hope that helps
Answer:
9b^8 + 24b^3 = (3b^3) [ 3b^5 + (8)]
greatest common monomial is 3*
Step-by-step explanation:
we see 9b^8 + 24b^3
there is a common factor here.
3b^3 so
9b^8 + 24b^3 = (3b^3) * 3b^5 + (3b^3) *(8)
9b^8 + 24b^3 = (3b^3) [ 3b^5 + (8)]
so...
