Here you have 2 linear equations and are to solve this system. Both equations have already been solved for y, so you can set one of them = to the other one:
-2x+11 = -3x+21.
Then 3x-2x = 21 - 11, or x = 10 (answer)
Find y by subst. x = 10 into either of the given equations.
Solution is then (10, ? )
Answer: 3617.28 cubic millimeters.
Step-by-step explanation: I used the formula of a sphere since a gumball is a shape of a sphere and plugged the radius into the formula.
I got that the volume of a single gumball is 288π cubic millimeters.
Since there are 4 gumballs, i multiplied the volume by 4.
The total volume of the four gumballs add up to be 1152π .
Lastly, I multiplied 1152 by pi
and got the answer to be 3617.28 cubic millimeters
