First you need to divide 7 and 15, and the answer you get is 8, so 8+7=15. 8 will be your answer.
4. 15 tens, 1 hundred, 5 tens
150
5. 18 tens, 1 hundred, 8 tens
180
note: I hope this helps. I haven't done this in a long time. Sorry X(
Hi Malik.
2x+4>14 or -(2x+4)>14
solve each inequality individually
you get
x>5 or x<-9
60 = 5k/7
420 = 5k
84 = k
m = 10(84)/10
m = 84
Hope this helps!
