Answer:
56.7 mi/h
Step-by-step explanation:
The formula for average speed is:
Average Speed = ![\frac{TotalDistance}{TotalTime}](https://tex.z-dn.net/?f=%5Cfrac%7BTotalDistance%7D%7BTotalTime%7D)
Thus we have:
Average Speed =
mph
<em>Rounding to the nearest tenth, we have </em>
Average Speed = 56.7 mi/h
notice that the denominator can be factored into (x-3)(x+3).
Now you can cross out (x - 3) from the numerator and denomiantor resulting in a simplified fraction of ![\frac{1}{x+3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bx%2B3%7D%20%20)
Plug the limit value (which is 3) into the simplified fraction.
Answer: ![\frac{1}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B6%7D%20%20)
135 because
15x1=15 15x7=105
15x2=30 15x8=120
15x3=45 15x9=135
15x4=60 15x10=150
15x5=75 15x11=165
15x6=90 15x12=190
A percent is a proportion of something that can come from a variety of different numbers depending on what you are measuring. 14.5% is not the same as 14.5 because the 14.5% isn’t necessarily 14.5 of a certain amount. For example, $14.50 of the $100 you have could be from your grandparents; making 14.5% of your money from your grandparents but a deposit of $145 into a bank account that already has $855 would mean that 14.5% of the money in that bank account was from that deposit but $145 does not equal $14.50. They just have the same proportion just different on different scales.

To find the amount he spent on bags of mulch you must take the cost of the shovel away from the total, giving the equation:
46.16-14.75=3.49x
To covert this to whole numbers, multiply by 100
4616-1475=349x
3141=349x
x=9
