My hand writing is messy but you would take. 40$ × 0.10 . then you would take 40$ and subtract it from the answer you received from multiplying and then you have your answer.
10 7/12 - 9/12=(10/12+7/12)-9/12=17/12-9/12=8/12
127/12-9/12
Nope. Her solution doesn't seem reasonable. In order to subtract 9/12 from 10 7/12 you must convert 10 7/12 to an improper fraction. You should then have 127/12 where she has 10/12.
Hope this helps! =)
Use distributive property
x^2+x-14+(-x+22)i
If you were to round it, a possible answer could be 9,997
