9(n+3)=7n-3
1) distribute 9 into (n+3)
9n+27=7n-3
2) subtract 7n on both sides
2n+27=-3
3) subtract 27 on both sides
2n=-30
4) divide by 2
n=-15
To solve for the distance the car is required to stop after the driver
steps on the break is by jus substituting the given value to the equation
given. Since the car is traveling at 50 miles per hour
24d = (50)^2

<span>D =104 ft</span>
Answer: Candace ate 
servings.
Step-by-step explanation:
Given: Candace ate 
cup of cereal.
The box of cereal states that 1 serving of cereal = 
cup.
i.e. 1 cup =

Hence, Candace ate servings.
She can buy a maximum of 80 cups.
