Question

100 points, (1-7, I need help with all of them please, you can explain stuff too)

1. "The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age. Nixon's first presidential election happened 39 years after the Great Depression. Using the given information, write an equation to find Raul's age, r."

2. "Rewrite the equation from part A by factoring the side that contains the variable r."

3. "Solve the two previous equations for r. What value does each equation give for Raul's age. Are the two values the same?"

4. "Raul's grandfather is Miguel, and Raul's sister is Paula. Raul's age is the same as his grandfather's age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from question 2, write an equation to find Paula's age, p, in years."

5. "Rewrite the equation from question 4 by factoring the side that contains the varible p."

6. "Solve the equation for p to find Paula's age. Express her age in years as a fraction."

7. "How many months old is Paula?"

Answer 1

Answer:

Raul's age is 15 years.

Step-by-step explanation:

r represents Raul's age.

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.

The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.

Therefore, 3r - 6 = 39

Add 6 to both sides.

3r = 45

Divide both sides by 3.

r = 15

Hence, Raul's age is 15 years.
