Answer:
Here's what I get
Step-by-step explanation:
Let's assume that the sandwiches are circular (because I couldn't find a good rectangular fraction maker.
Toni ate ¾ of a medium sandwich (Figure below).
Mary Jo ate ⁶/₈ of a medium sandwich.
Mary Jo ate the same amount as Toni, because ¾ = ⁶/₈
Becky ate ¾ of a small sandwich and Toni ate ¾ of a medium sandwich.
Becky ate less than Toni, because ¾ of a small amount is less than ¾ of a large amount.
Answer:
x=19
DE=84
EF=36
reasoning:
the sum of DE and EF is 120, so to find the value of each first you find x
find x by adding DE and EF
this gives you the equation (4x+8)+(2x-2)=120
combine like terms and get 6x+6=120
subtract 6 from both sides to get 6x=114
divide both sides by 6 to get x=19
plug 19 into x in both equations to get the values of each length
9m +18= -6m -42
9m +6m= -42-18
15m = -60
m= -4
