So just add equation 1 and equation 2
You will get
2x-2x + 5y + 3y = 12 + 4
8y = 16
y = 16/8
y = 2
Substituting y in equation 1
2x + 5*2 = 12
2x + 10 = 12
2x = 12 - 10
x = 2/2
x = 1
=
Answer:
could be wrong. but I belive its B
Step-by-step explanation:
7 X 2 = 14 x pi (3.14) = gives us 43.96. since its 4 tall. you would muiliply 43.96 x 4. it would give you 175.84.
here is the formula because I want you to understand this.
R = radius
D = 2 x radius
Pi = 3.14
C = circumference
C = Pi x (radius x 2)
Answer:
Step-by-step explanation:
-6 is rational because it can be written as a ratio -6/1 for example
