Question

This is urgent...please help!

the brown family is ordering pizza. they are trying to decide whether to order a large pizza or a monster pizza. a monster pizza (m) has six fewer slices than twice the number of slices on a large pizza (l). the difference between the number of slices on a monster pizza and the number of slices on a large pizza is five slices. which system of equations below can be used to determine the number of slices on a large pizza and a monster pizza?

a) m - 2 l = 5
m - l = 6

b) 2m - l = 6
m - l = 5

c) 2m - l = -6
m - l = 5

d) m - 2 l = - 6
m - l = 5

Answer 1

d) m - 2 l = - 6; m - l = 5

Explanation:

Twice the number of slices on a large pizza is 2l. 6 fewer than that is 2l-6. This is the number on a monster pizza, so we have ...

m = 2l -6

Subtracting 2l from both sides gives the equation ...

m -2l = -6 . . . . . matches choice D
