Answer:
x = 7 and y = 0
Step-by-step explanation:
We can either solve by substitution method or by elimination method or both method . We will solve by both the elimination and substitution method.
X+y=7 ---------------------------------------------------(1)
-x+y=-7 -------------------------------------------------(2)
Subtract equation (2) from equation(1)
2x = 14
Divide both-side of the equation by 2
2x/2 = 14/2
x = 7
Substitute x = 7 into equation (1)
x+y=7
7 + y = 7
Subtract 7 from both-side of the equation
7-7 + y = 7-7
y = 0
x = 7 and y =0

Answer:
A. The volume is the product of the area of the base, 5x(x + 3), and
the height, 2x - 1.
Step-by-step explanation:
Volume is defined as the product of the Length, Width, and Height,
V = L*W*H
The Length x Width is the <u>Area of the Base</u>
<u></u>
L*W = Area Base)
Therefore:
The (L*W) in the equation V = L*W*H can be replaced with [Area of the Base]
[A<u>rea of the Base]</u>
[A<u>rea of the Base]</u> = (5x)*(x+3) [(or 5x^2 + 15x)]
Volume = [A<u>rea of the Base]</u>*H
Volume = [(5x)*(x+3)<u>]</u>*(2x-1)
The volume is the product of the area of the base, 5x(x + 3), and
the height, 2x - 1.
That looks a lot like the answer in A: "The volume is the product of the area of the base, 5x(x + 3), and the height, 2x - 1."

This question is asking us to add the numbers together to create the sum of drinks.
210 + 195 = 405
Why tho?
1 : 0 + 5 = 5
2 : 1 + 9 = 10 Carry the one.
3 : 2 + 1 = 3 + 1 = 4
=405
Hope helps!-Aparri
