Answer:
A. y(3) + x = total cost
B. Shoe rental is $2.
Step-by-step explanation:
A. 4(3) + 2 = 14
B. If 4(3) = 12, and the total cost is $14. Then the shoes cost $2.
4(3) = 12 + 2 = 14
A) 4 cm
B) 9 cm x 12 cm
C) 108 cm
I think it is possibly point b
-2x+y=5
x-3y=-30 so you can multiply the bottom equation by 2 you'll get 2x-6y=-60
-2x+y=5
2x-6y=-60 And subtract the equations. You'll get -5y=-55 y=11. Plug it in to one of the original equations. -2x+(11)=5
-2x=-6 so x=3
y=11 and x=3
