A craft store sells clay in spheres with radius r. A sculptor uses these spheres of clay to create composite figures. How many copies of the figure can the sculptor make from 15 spheres of clay? Explain.
-
The sculptor can make _ copies of the figure with 15 spheres of clay because the volume of each sphere of clay is _ and the volume of the figure is _

the answer is. -82562234434584

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
