To find the sales price of the DVD, you would multiply the price and sale percent to get the sale price.
You would need to turn 20% into a decimal to multiply it with 9, so you would move the decimal place two times to the left: From 20. to→ .20
In this case: 9 × .20 = 1.8
Then you would subract the sub price by the sales price
9 - 1.8 = 7.2
The sales price of the DVD would be $7.20
X - y = 5....x = 5 + y
6x = 8y
6(5 + y) = 8y
30 + 6y = 8y
30 = 8y - 6y
30 = 2y
15 = y
x - y = 5
x - 15 = 5
x = 15 + 5
x = 20
ur 2 numbers are : 20 and 15
It’s 46 hope that helps I don’t know how to put a picture of the work I did on here but I ta 46
57.8 ≈ 60
81 ≈ 80
57.8/ 81
≈ 60/80
≈ 3/4
≈ 0.75
The quotient 57.8/ 81 is approximately equal to 0.75~
Option B is the most logical answer in accordance to the Law of Large Numbers.
In the theory, it states that the average of results obtained from a large sum of trials should be close to the expected value.
