Question

Sherrie has twice as many pairs of sneakers than manuel. together they have 90 airs of sneakers. how many pair does sherrie have?

Answer 1

sherrie has 60 and manuel has 30

Answer 2

So if they have 90 pairs of sneakers together. You could say; 3x = 90
( this 3x comes from Sherrie’s twice, 2, and Manuel himself )

this would give us x = 30, but since she has twice as much as him. you double this to get 60.

so Sherrie will have 60 shoes and Manuel will have 30.
