To do this problem you would set up an equation, x/550=90/100. You would then multiply 550 by 90 and then divide that answer by 100. This would get you the answer 495.

550 *0.9 = 495 Does this make sense? Do you need any further explanation?<span />

Megan hiked 15.12 miles in 6.3 hours. If Megan hiked the same number of miles each hour , how many miles did she hike each hour?
OLEGan [10]
To find how many miles per hour, we divide the number of miles hiked by the number of hours it took to hike them.

=15.12 miles ÷ 6.3 hours
=2.4 miles hiked per hour

You have quarters and dimes that total $2.80. Your friend says it is possible that the number of quarters is 8 more than the num
AnnyKZ [126]

Answer:

Step-by-step explanation:

d = number of dimes

2.80 = 0.1d + 0.25 (d + 8 )

2.80 = 0.1d + 0.25d + 2            Combine like terms

2.80 = 0.35d + 2                       Subtract 2 from both sides

0.80 = 0.35d                             Divide both sides by 0.35

d ≈ 2.29

No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.
