-x - 3y = -12
-x = 3y - 12..multiply by -1 to make x positive
x = -3y + 12
so u would sub in -3y + 12 for x in the first equation
Turn 39% into a decimal
0.39
"of" means to multiply
so we get
0.39 * 72 = x
The answer is 27.001 because .001 comes before .002

Answer:
12 inches
Step-by-step explanation:
Given data
Height= 11 inces
Volume= 4,973.76 cubic inches.
The expression for the volume of a cylinder is
V= πr^2h
substitute
4,973.76= 3.14*r^2*11
4,973.76= 34.54r^2
r^2= 4,973.76/ 34.54
r^2= 144
Square root both sides
r=√144
r=12 inches
