Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

Chapter 1.2, Problem 27PPS

To determine

To evaluate: the given expression

Expert Solution & Answer

Answer to Problem 27PPS

The numerical value of the given expression is 18

Explanation of Solution

Given:

ac3−15

a=9,b=4 and c=11 .

Calculation:

Given the expression

ac3−15 , we first substitute c = 11 and a = 9.

ac3−15=9×113−15=9×11÷3−15

Since, there are three operations subtraction, multiplication and division, so according to the rules for order of operation, by step 2 look at the expression to see which operation comes first from left to right multiplication or division.

Since multiplication comes first, multiply first and then divide.

9×11÷3−15=99÷3−15=33−15=18

Conclusion:

Therefore, the numerical value of the given expression is 18.
