Answer:
x,y =2,1
Step-by-step explanation:
3x+4y=10 ................equ1
x-y=1 ................equ2
This system of equations forms a quadratic equation.
Lets use the substitution method in solving this set of equations
from equ 2; x=y+1
substitute x=y+1 into equ 1
3(y+1) +4y=10
3y+3+4y=10
7y=10-3
7y=7
y=7/7
y=1
but x=y+1
substitute the value of y into this equation to get x
x= 1+1
x=2
x,y=2,1

Answer:
The volume of ball is <u>33.5 inches³</u>.
Step-by-step explanation:
Given:
Jackie bought a game that contained a ball of 10 jacks. The ball had a radius of 2 inches.
Now, to find the volume of the ball.
As, the ball is in spherical in shape.
Radius(r) of ball = 2 inches.
Now, to get the volume we put formula of sphere:
<em>Taking the value of π = 3.14.</em>
<u><em>So, the volume of ball rounding to nearest tenth = 33.5 inches³. </em></u>
Therefore, the volume of ball is 33.5 inches³.
