Answer:

F=10

Step-by-step explanation:

Add 13.5 and 14 to get 27.5.

2.25f+5=27.5

Subtract 5 from both sides.

2.25f=27.5−5

Subtract 5 from 27.5 to get 22.5.

2.25f=22.5

Divide both sides by 2.25.

f=  

2.25

22.5

​  

 

Expand  

2.25

22.5

​  

=10 by multiplying both numerator and the denominator by 100.

f=  

225

2250

​  

 

Divide 2250 by 225 to get 10.

f=10
