Answer:
50
Step-by-step explanation:
Assuming you're solving for Q, the first step is to multiply the first set of parenthesis by 0.10:
0.10(72-Q) = 7.2 - 0.1Q
The next step is to combine the terms that have Q in them:
7.2 - 0.1Q + 0.25Q = 14.7
7.2 + 0.15Q = 14.7
Now isolate 0.15Q:
0.15Q = 14.7 - 7.2
0.15Q = 7.5
Divide 7.5 by 0.15 to solve for Q:
Q = 7.5/0.15 = 50

Answer:
24
Step-by-step explanation:
use Pythagoras theorem
a^2 + b^2 = c^2
18^2+b^2=30^2
b^2 = 30^2 - 18^2
b = √576 =24
