The answer is x=22.96
Step-by-step explanation:
hope that helps
67.52=21.6+2x
67.52=2x+21.6
2x+21.6=67.52
2x+21.6−21.6=67.52−21.6
2x=45.92
2x/2=45.92/2
x=22.96
Answer:
yard
Step-by-step explanation:
Length of string Mrs. Ruiz has =
yard
Mrs. Ruiz needs to hang 3 banners using the string.
Having known that each banner uses same length of string to be hung we can divide total length of sting into 3 equal parts.
So, we can divide
yard by 3 as
⇒ 
Changing the division sing to multiplication by taking reciprocal of divisor.
⇒ 
We can now multiply numerators and denominators.
⇒
yard
∴ Mrs. Ruiz must used
yard of string for each banner.
It is not a function because there can't be two of the same number on the x-axis.
