To solve this problem, you'll want to use the AC method to factor x^2+7x-30.
After factoring your expression will look like this:

Cancel out the x+10 because they are common factors, so you are just left with the simple x-3.
Answer is:
x - 3
Answer: speed = 585/(13/2) = 90 miles per hour.
Step-by-step explanation:speed = distance / time
since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2
100
Why:
125-25 is 100
25-25 is 0 so it’ll give you 100

Answer:
She earned $20 in tips.
Step-by-step explanation:
First, you need to work out how much pay she'd get for 12 hours work:
12 x $11.25 = $135 for 12 hours work
Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:
2/5 of $11.25 = $4.50
Add both these sums together to get her total pay for hours worked:
$135 + $4.50 = $139.50
Subtract that sum from her total pay to find out how much money she earned in tips:
$159.50 - $139.50 = <u>$20</u>
