Hope it helps :) and let me know if you want me to elaborate.
Answer:
x = 9
Step-by-step explanation:
(3x - 21) = (2x - 13) eliminate by subtracting 2x and add 21 on both sides
x = 9
There is no way to factor this so i would assume the answer is no solution.
Answer: y=1x+9

Answer:
The volume of the ball is 256 cm³
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for V
The volume is equal to the ratio of the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
