A car traveled twice as fast on a dry road as it did making the return on a slippery road. the trip was 60 mi each way, and the round trip took 35 hr.
Answers
Let x represent the hours taken on the dry road. Slippery road was then 2x. 2x + x = 3x. 35 / 3 = 11.66… = x.
So, on the dry road, the car took 11.66… hours.
For the slippery one, 2 * 11.66… or 23.33… hours.
Convert to mph, shall we?
Dry road:
30 miles / 11.66… hours = 2.57… mph.
Slippery road:
30 miles / 23.33… hours = 1.28… mph.
If that’s what you’re looking for — you never quite asked.

This is Accounting math, so congrats at being in college level math!
Now let's solve this! :)
The Book Value of an asset is the asset's cost minus the assets accumulated depreciation.
Asset's costs:
Purchase of equipment = $18,000
Shipping costs = $620.00
Installation costs = $590.00
Total = $19,210.00
Assets accumulated depreciation:
depreciation per year=(Cost of equipment-Salvage Value) ÷ Estimated Useful Life = (18000 - 2000) ÷ 10 = $ 1,600 per anum (per year)
Cost: $18,000
Salvage Value: $ 2,000
Estimated Useful Life: 10 years
With this data, we can make the following chart provided below.
Looking at the chart we can conclude that hence, in the 10th year, the accumulated depreciation value is $ 16,000.
So the Book Value at the end of year 10 is...
an asset is the assets cost - the assets accumulated depreciation.
$19,210.00 - $16,000 = $ 3,210

60 is what percent of 72
60 = x% of 72
60 = x% * 72
60 = x/100 * 72
60/72 = x/100
x = 60/72 * 100
x = 83.33%
The correct result would be 83.33%.
60 divided by 12 is 5, and 72 divided by 12 is six.
5/6 equals 0.83
0.83 x 100 is 83, or 83%.
Brainiest would be nice.

c - cookies
m - muffins
c + m = 27
3c + 7m = 129
I don’t know how to explain how to do efficiently but I just plugged in numbers until it worked:
3(15) + 7(12) = 129
45 + 84 = 129
Answer:
You sold 15 cookies and 12 muffins
Step-by-step explanation:
So you're given that 1 cookie is sold for $3 and 1 muffin is sold for $7
You're also given that in total you made $129, and sold 27 items
Let's make equations from that, letting c stand for amount of cookies and m for amount of muffins.
- 3c + 7m = 129 (equation for amount of money made)
- c + m = 27 (equation for amount of items sold)
Now we can use the second equation to find m:
c + m = 27
m = 27 - c
Not we can substitute m into the first equation to find c:
3c + 7m = 129
3c + 7(27-c) = 129 [substitute m for (27-c)]
3c + 189 -7c = 129 [distribute 7 into (27-c)]
-4c + 189 = 129 [combine like terms]
-4c = -60 [subtract 189 from both sides]
c = 15 [divide both sides by -4]
Now we can substitute c into the second equation to find m:
c + m = 27
15 + m = 27
m = 12
