Answer 1

Answer:

1. d = -6 2. n = -80

Step-by-step explanation:

If you divide 42 by -252 you get -6. And if you use your mental math you see that two negatives make a positive then you see it has to be negative and 80/4= 20 than -80/-4 = 20. Hope this helps, let me know if correct, and have a great day!!

Answer 2

Answer:

42d = -252 (since 42 is multiplied by d, you have to divide by 42 on both sides to get what d is)

d= -6

20 = n / (-4) (since n is being divided by -4, you have to multiply by -4 on both sides to get what n is)

n= -80

Step-by-step explanation:

to get what the variable is, you have to "undo" the operation that is being done.

Jeremy wanted a new drum set for $600. The drums had a scratch on them, so they were discounted down to $492. By what percent did the drums decrease?

Answers

Answer:

18%

Step-by-step explanation:

First you find the difference between 600 and 492 which is 108. Then you divide that difference by the original cost which is .18. Then you multiply that by 100 which is 18%.

It would be 18%.

First you need to find the difference between 600 and 492 which is 108.
Then you need to divide 108 by 600 which is 0.18.
Then you need to multiply 0.18 by 100 which leaves you with 18%.

A number changes from 50 to 76. What type of percent change is this? Calculate the percent change.

Answers

Answer:

50 is the old value and 76 is the new value. In this case we have a positive change (increase) of 52 percent because the new value is greater than the old value.
This is a positive increase

You need to find the difference between 50 and 76 which is 26.
Then you do 26/50 which is 0.52. Multiply 0.52 by 100 and that leaves you with 52.

The percentage increase is 52%.
