1) x+y = 170
x-y = 26
2) Subtract the two equations from each other. Doing this you get 2y = 56.
So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.
x-28 = 26
x = 54
3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).
Answer:
y = -2x - 8

Answer:
V=33.51in^3
Step-by-step explanation:
5inch-1 in
=4inch
divide by 2 because the problem gives diameter, not radius. (radius is half of diameter)
The space inside is a sphere so it will be
V=4/3πr^3
V=4/3*pi*(2)^3
V=33.51 inch cubed
38 42 34 54
