Answer:
x = 14 and 2/3
Step-by-step explanation:
Make an equation where x is the number.
2x - 15 = 7 + 1/2x
Then, solve the equation.
multiply both sides by 2 to get rid of the fraction
4x - 30 = 14 + x
subtract x from both sides
3x - 30 = 14
add 30 to both sides
3x = 44
divide both sides by 3
x = 14 and 2/3
Answer:
yard
Step-by-step explanation:
Length of string Mrs. Ruiz has =

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.
