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.
Multiple the first equation by 1.5 and solve the equation then
Answer:
20i² + 38i
Step-by-step explanation:
4i(7+6i)+2i(5-2i)
28i + 24i² + 10i - 4i²
24i² - 4i² + 28i + 10i
20i² + 38i

Step-by-step explanation:
csc∅tan∅
(1/sin∅)(sin∅/cos∅)
(sin∅)/(sin∅cos∅)
1/(cos∅)
