Please help Maggie's brother is 3 years younger than twice her age. The sum of their ages is 30.
denpristay [2]
I’m not sure if this is correct but this is the way i would solve it.

first, make an equation with the given information

2x-3=30

Then, add three to both sides

2x=33

Finally, divide both sides by 2

x= 16.5


x represents the age of maggie so all you have to do is plug the solution into the equation to check your answer.

2(16.5)-3= 30

Answer:

10.

Step-by-step explanation:

Since 60 is the profit you need to make, you plug in 60 into P(x). So, you get the equation 60=0.3x^{2}+7x-40. The answer to this equation is 10. I think this is the correct answer.
