Answer:
22
Step-by-step explanation:
the equasion would be e=(m*2)-4
then the new one would be m= (e+4)/2 and e=18
18+4=22/2=11
to check this do 11*2=22-4=18

Answer:
a)

b) l=19.2 units
Step-by-step explanation:
a)Let F represent the force and l represents the length of the wrench handle.
Then inverse variation relation is:

When we introduce the variation constant, we get:

From the question when F=96, l=12


The equation is

b) If a person can only exert 60 pounds of force on a wrench,then



Hence the length of the wrench must be 19.2 units
