The answer is B
2x+5y=3(1) times it by 1
-x+3y=-7(2) times it by 2
____________________
2x+5y=3
-2x+6y=-14
__________
11y=-11
Y=-1
Now we have to found x..... you have to plug in -1 in 2x+5y=3...
2x+5(-1)=3
2x-5=3
2x=3+5
2x=8
X=8/2
X=4
There are your 2 solutions... hope you understand
Area of a circle = pi * r^2
Radius (r) = ½ * diameter
½ * 10 = 5
A= pi * 5^2
25 * pi = 78.54 sq inches
10.99 / 78.54 = about 14 cents per sq in (13.99)
Do you have to find the angle or the measurement?
Well if you’re looking for y then
x=4y + 7
-4y
x-4y=7
-x. -x
-4y=-x+7
_______
-4. -4. -4
y= 4x - 7/4
i’m pretty sure :)
