Which is the better buy if 4 cars cost 12 dollars and 3 cost 11 pls explain

4 cars for 12 dollars

Step-by-step explanation:

see when trying to find the better deal you have to divide the amount that is being paid by the amount of items being bought, so 4 cars for 12 dollars is 12/4 which is 3, you are paying 3 dollars per car where as 3 cars for 11 dollars is 11/3 which is 3.66 so you are paying $3.60 per car therefore 4 cars for 12 dollars is the better deal

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

y -5 = (-1/4)(x + 8)
