.8 (88%)+.2x=90%
70.4%+.2x=90%
subtract 70.4% from 90% to get 19.6%
make the .2x into 2 and the 19.6 into 196
divide 196 by 2 to come up with the answer of 98%.
you will need a 98% to have a 90% for the final grade
15% x 50 = 7.5
You can search these up in a calculator or in google if you want. The answers should be online.
72/8 +3*4 - 105 /5
= 9 + 12 - 21
= 21 -21
= 0
Answer:
