What is the missing side 7.5 in and x

Answer:
The missing side is 18 inches
Step-by-step explanation:
Since in the smaller rectangle the sides are 2.5in x 6in and one side for the larger rectangle is given, you can make an equation.
[tex]\frac{2.5}{6}=\frac{7.5}{x}[/tex]
Then you can cross multiply.
2.5x=45
Divide by 2.5 on both sides.
x= 18
Answer:
18
Step-by-step explanation:
if it is a ratio like 2.5:6 the the answer will be 18 because if you do 2.5 over 7.5 that comes out to a total of 0.33 and thats rounded so if you do 6 over .33 then the answer will be 18
