Answer:

Option B is the answer.

Step-by-step explanation:

Actual cholesterol level of Brain was 220.

He reduced his cholesterol level by 20% By following a strict diet and regular exercise.

So we have to calculate current level of his cholesterol.

Since 20% of 220 = \frac{220*20}{100} = 44

So after reduction of 44 units cholesterol level will be 220 - 44 = 176

Option B 176 is the answer.

220 x 20% (.20) = 44
220-44=176

What is the value of h in the equation 8h = 60
irga5000 [103]

Answer:

h= 7.5

Step-by-step explanation:

8h=60

One solution was found :

                  h = 15/2 = 7.500

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    8*h-(60)=0

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  8h - 60  =   4 • (2h - 15)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    2h-15 = 0

Add  15  to both sides of the equation :

                     2h = 15

Divide both sides of the equation by 2:

                    h = 15/2 = 7.500

One solution was found :

                  h = 15/2 = 7.500
