8. three friends each bought two slices of pizza and a drink at the mall. if drinks cost $0.75,
and the total of their order was $11.25, how much did one slice of pizza cost?

one slice of pizza costs 3 dollars.

Step-by-step explanation:

you multiply 0.75 by 3.

subtract 2.25 by 9

divide 9 by 3

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
