Answer:
b = 5/12
Step-by-step explanation:
You have the proportion
1/(3b) = 4/5

Answer:
0
Step-by-step explanation:
21(3) +2(7) - 11(7) because the absolute value of -11 is 11
63+14-77
=0

Taking commen 2 in RHS
p = 2 (L+W )
Divide by 2 on both sides.
p/2 = L+W
Subtract W on both sides.
p/2 - W = L
or L = p/2- W
