Answer:

x=291/76

Step-by-step explanation:

Convert:

1/2x(6x+ 1/2)=-0.8x+16-1.2

Remove parenthesis and move terms:

3x+1/4=-0.8x+14.8

Collect the like terms and convert:

3x+0.8x=14.8-1/4

Subtract the fractions:

3.8x=74/5-1/4

Divide both sides by 3.8:

3.8x=291/20

x=291/76

The amount of force one exerts on a wrench handle to loosen a bolt is inversely

Inessa [10]

Answer:

$F = \frac{1152}{l}$

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:

$F\propto \: \frac{1}{l}$

When we introduce the variation constant, we get:

$F = \: \frac{k}{l}$

From the question when F=96, l=12

$96= \: \frac{k}{12}$

$k = 1152$

The equation is

$F = \: \frac{1152}{l}$

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

$60 = \frac{1152}{l}$

$\implies \: l = \frac{1152}{60}$

$l = 19.2$

Hence the length of the wrench must be 19.2 units
