Question

Chapter 1.8, Problem 1MRE

To determine

To Evaluate: The expression 3ab−2x if a=2 , b=5 , c=4 , x=3 , and y=7

Expert Solution & Answer

Answer to Problem 1MRE

The value of the expression 3ab−2x is 3ab−2x=24

Explanation of Solution

Given information:

The expression 3ab−2x and the values a=2 , b=5 , c=4 , x=3 , and y=7

Concept Used:

The value of an expression at the given values of the unknowns is calculated by substituting the given values of the unknowns into the expression and simplifying it.

Calculation:

Given the expression 3ab−2x and the values a=2 , b=5 , c=4 , x=3 , and y=7

Evaluating the expression 3ab−2x at a=2 , b=5 and x=3 , we have

3ab−2x=3(2)(5)−2(3) Substituting a=2, b=5, x=3=30−6 Multiplying=24 Subtracting

Therefore, 3ab−2x=24

Conclusion:

The value of the expression 3ab−2x is 3ab−2x=24
