Which of these systems of equations would be best solved using the subtraction method? |. 2x - 7y + 3y =
– 6 - 6x - 4y = - 38

||. 2y = - 6x + 7x-1
y = 2x-5

|||. – 7x + 3x + 2y = -6
4x - 6y = – 38​

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

tip $2.90

total $17.40

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
