Answer:

The new volume is 7^3 or 343 times the old volume

Step-by-step explanation:

The original sphere has a volume of

V = 4/3 pi r^3

The radius is multiplied by 7

The new volume is

V = 4/3 pi (7r) ^3

V = 4/3 pi (7)^3 r^3

The new volume is 7^3 or 343 times the old volume

How to solve by elimination2x-y=32 and y -5x=13

erik [133]

2x-y=32
y-5x=13

transform the second equation to make the elimination possible
2x-y=32
-5x+y=13

now, our ys match, and we can drop them out

2x-y=32
+
-5x+y=13
 -3x+0=45

x= -15

Now we use the meaning of x in one of the original equations

2*(-15)-y=32
-y=32+30
y=-62

The answer is (-15;-62)
