How do I factor out the coefficient of the variable -5p+20

Answers

Answer 1
Answer: -5(p-4)

think of dividing each term by whatever you're factoring out, so the -5/-5 becomes a 1, and the +20/-5 becomes -4

Answers

D 100 METERS IN 2 MINUTES

Rate = Distance / time = 100 m / 2 minutes

Thus, the answer is (D) 100 meters / 2 minutes.

In 1984, a 12-ounce box of cold cereal cost $0.89. In 2008, an 18-ounce box of the same cereal sold for $3.29. How much more was the cost of the cereal per ounce in 2008 than in 1984? Explain

Answers

Well, we can just divide them.

0.89 / 12 is approximately $0.07

3.29 / 18 is approximately $0.18

0.18 - 0.07 = $0.11

So the cost of cereal in 2008 is 11 cents more per ounce than the cereal in 1984.
Firstly we need to find out how much is worth 1 ounce of cold cereals both in 1984 and 2008. Do do that we may just divide both numbers by 12:

0.89 ÷ 12 ≈ 0.07 (I rounded it to the neaerest cent as we're talking about money anyway)
3.29 ÷ 18 ≈ 0.18

So in 1984 one ounce costed $0.07, while in 2008 it costed $0.18.

To find out how much more was it in 2008, we just need to do the substraction:

$0.18 - $0.07 = $0.11

Answer: The cost of the cereals per ounce was bigger in 2008 than in 1984 by $0.11.

Allison and her husband Noah both get in their cars and begin to drive at the same time. Allison starts 360 mi from their home and drives directly home at a constant rate of 50 mph. Noah starts at their home and drives away from the home at a constant rate of 40 mph. The system that models this situation is given, where d represents the distance from home, and t represents time, in hours. The solution to the system is (4, 160).

What is the correct interpretation of the solution to this system?

d = 360 - 50t
d =40t

A. Noah will be 160 mi from home and Allison will be 4 mi from home.

B. Allison and Noah will both be 160 mi from home after 4 h.

C. Noah will be 4 mi from home and Allison will be 160 mi from home.

D. Allison and Noah will both be 4 mi from home when they drive for 160 min.
