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:
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.

1.What happens when fertilizer ends up in waterways?
2. Describe eutrophication.
3. What has happened at the mouth of the Mississippi River?
Answer:
1.When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.
2.Eutrophication is a significant increase of algae (microscopic organisms similar to plants) due to the greater availability of one or more growth factors necessary for photosynthesis, such as sunlight, carbon dioxide and nutrients (nitrogen and phosphorus)
3. I don't know I am way to tired sorry
Step-by-step explanation:
1. When manure or fertilizers enter water, the nutrients they release stimulate microorganism growth. These microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in water, fish and other animals living in water suffocate.
2. Eutrophication is the process by which water bodies are enriched with minerals and nutrients.

rewrite [tex]-2x+3y=-15[/tex] in slope-intercept form
Answer: [tex]Y = \frac{2}{3} x - 5[/tex]
Step-by-step explanation:
Answer: y=7.5+-5
Step-by-step explanation:
Divide 3y from itself and -15 to cancel out the Y variable. So Y is equal to -5. Then you would be left with -2x=-15. So then you would have to divide -2x from itself and -15, which would give you 7.5, and that is your x variable.

(2) Clare said that 4/3:5/2 is 10/3. She reasoned: 4/3.5=20/3 and 20/3:2=10/3.
Explain why Clare's answer and reasoning are incorrect. Find the correct
quotient!
Answer:
The answer is 8/15
Step-by-step explanation:
4/3 divided by 5/2 is the same as 4/3 times 2/5
4/3 times 2/5= 8/15
8/15 is the answer
She is wrong because if you want to do it you have to multiply the fraction with 5 and then MULTIPLY it by 2 not divide it by 2.
Hope this helps :)
