If it has only one solution that means that there is only one value of x that will fulfill this equation
35 - 5x + 6x - 36 = -24 - 17x + 17x + 24
-5x + 6x - 36 = -24 -17x + 17x + 24 - 35
x - 36 = -24 + 24 - 35 (I just canceled out the 17x because it would have justy made the process longer if I moved them over)
x = -24 + 24 - 35 + 36
x = -35 + 36
x = 1
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
The degree of the expression is 2.
The answer is C. 91.46 !!!
