Answer:
$7.20
Step-by-step explanation:
First, we would have to find out how much to subtract from $62.
We need to multiply 90% and 62 or 0.9 x 62
When we finish this equation we get 54.8, which is what we need to subtract from 62 to see what 90% off is.
62 - 54.8 = 7.2, so therefore our answer is $7.20
Problem 1 Answer: x = 2/3y+8
Show Work:
Step 1: Add 2y to both sides.
3x−2y+2y=24+2y
3x=2y+24
Step 2: Divide both sides by 3.
3x/3 = 2y+24/3
x = 2/3y+8
Problem 2 Answer: x=−2y+48
Show Work:
Add -2y to both sides.
x+2y+−2y=48+−2y
x=−2y+48
The true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.
<h3>How to explain the cost?</h3>
In this situation, the function is f (t), when t is a value between 0 and 30. The cost is $0 for the first 30 minutes
When t is a value between 30 and 90, the cost is US$ 5 if the connection takes between 30 and 90 minutes.
Here, the true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.
