Question

Select the correct answer. Sam's height is 15 centimeters less than 2 times Martha's height. If Sam is 185 centimeters tall, and Martha's height is x, the relationship between the heights can be represented by the equation 2x − 15 = 185. What is Martha's height? A. 90 B. 95 C. 100 D. 105

Answer 1

C. 100

Step-by-step explanation:

If Sam is 15 centimeters less than 2 times Martha's height and his height is 185.

185 is 15 centimeters less than 200 and 200/2 is 100

Martha is 100 centimeters.

Answer 2

To solve the equation 2x − 15 = 185, we need to isolate x on one side of the equation.

Adding 15 to both sides gives:

2x = 200

Dividing both sides by 2 gives:

x = 100

Therefore, Martha's height is 100 centimeters.

The correct answer is (C) 100.
