13. Four observations:
1. m<SWT = 90° (given)
2. QW = TW (given)
3. m<RWS = m<UWV (vertical angle pair)
4. m<RWU = 180° (straight angle)
Answer:
off topic- and I'm sorry for that- but hi stay- :)
1. You convert all the numbers into decimals.
a. For 8 1/9 you multiply 8x9 and add the numerator which in this case is one, so the equation would be 8x9=72 then 72+1= 73
b. For 81/10 I used a calculator for accuracy and I just divided 81 by 10 because the fraction line can also be used as a division sign. For this I got 8.1
2. Now I looked at all the numbers I had including the fractions I converted to decimals... 8.115, 8.55, 73, and 8.1
3. Lastly, I put the numbers in order from least to greatest: 8.1, 8.115, 8.55, and 73
4. In order to figure out which one is the smallest and largest, I just added zeros on the end of the numbers so they would all be the same: 8.1-->8.100, 8.115 I kept the same because it already had 3 decimal places, 8.55--> 8.550, and 73--> 73.000
5. Then i could tell which number was the largest by the decimal place numbers.
**Hope this was helpful... It's kind of hard to explain online but hopefully you have a better understanding of how to do it!**
Alright, so the equation we have here is 22.75x+32=128.69
Now we just solve
-32 on both sides, we get
22.75x=96.69
divide by 22.75 on both sides we get
x=4.2501989
So 4 hours
You add the 4.25 hours
10, 11, 12, 1 is the hour
And .25 is a fourth, and a fourth of 60 minutes is 15 minutes
So he left at 1:15 pm
