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:
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
