Question

# If m = 8, then what is the value of 12m – 8?

## 88    99    110    22 Hint:

## The correct answer is: 88

### The given expression is 12m - 8There is one variable and two constants in the above expression. The variables is : ’m’. Value assigned to the variable is are m = 8. We have to substitute this value and find the final value of the expression.There are two terms in the above expression. The first term is ‘12m’. We have to multiply m by 12.Second term is constant.There is ‘-’ sign between the terms. So we have to subtract from the first term.We have to first substitute the value and perform the required operations.To substitute the value, we have to replace m by 8. After substituting the value, we will get the following equation:12m – 8 = 12(8) – 8We will do the multiplication first.12m – 8 = 96 – 812m – 8 = 88Therefore, the value of equation is 88So option which is ‘88’ is the right option.

We have to be careful about the operations because of the variables. We have to follow the proper procedure for performing the operations. The variables take different values under different conditions. So we have to be careful while substituting the values. The main part of this type of question is just replacing the variables by their values and performing the operation.
