Perform the indicated multiplication first: -15 + 5q + 4 = 5q - 11
Note that 5q appears on both sides of this equation. Cancelling, we get :
-11 = -11. This is always true. Thus, -5(3-q) +4=5q-11 is true for all q.
y = 1x + 3, also y = 1x + 4 both of those are parallel
She regrouped the numbers instead of multiplying like 8b(2b-r) -4r(2b-r).
Answer- You can get 10 Small rafts
12 x 100+ 1200
1600-1200=400
400/40 =10 Rafts
