Answer:
4 hours
Step-by-step explanation:
Since the company was able to produce 15 book in 3 hours, that mean they produce 5 book every hour. So adding 5 more books to 15 to get 20 means that you add one more hour. So it would be 4 hours! hope this helps!:)
Hola!
I just wanted to say Goodluck! :)
D = m/v
v*d = v*(m/v) ... multiply both sides by v
v*d = m
(v*d)/d = m/d ... divide both sides by d
v = m/d
--------------------------------
After we solve for v (aka isolate v), we end up with this final answer
v = m/d
Step-by-step explanation:
17) 3x+5-12+4x+2x
3x+4x+2x +5-12
8x-7
if x =6
8*6-7 =48-7
= 41
18.) 9(3x-4y+8)
27x-36y+72
