Answer:
261.3cm3
Step-by-step explanation:
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.
40% means 0.4 .
So . . . . . 7 = 0.4 N .
Divide each side by 0.4 . . . N = 7/0.4 = 17.5
