Question

Carl is seventy-three inches tall. This is twenty-one inches less than two times Marcia's height. How tall is Marcia?

Answer 1

Answer:

Marcia is 47 inches tall.

Step-by-step explanation:

Let's solve this step by step and try to visualize the situation.

• Carl: 73 inches tall

The second part of the question states that Carl's heigh is twenty-one inches less than two times Marcia's height. Add 73 + 21 to equal 94. Since Carl is 21 inches less that means that Maria is 21 inches more ( so that's why I added instead of subtracting) because we are trying to find Maria's equation.

Let x be Marcia's height

2x = 94

• The question staes that 73 is 21 inches less than two times Marcia's height which means that the equation 2x = 94 applies because 73 + 21 = 94

After simplifying the equation, we can get the answer that Marcia is 47 inches tall.

Answer 2

Answer:

Step-by-step explanation:

Givens

Carl  = 73

Marcia = 2x - 21 = 73

Solution

2x - 21 = 73                           Add 21 to both sides.

2x = 73 + 21                          Combine

2x = 94                                 Divide by 2

2x/2 = 94/2

x = 47
