9u-9t=18
original no. is 10t+u
reversed no. is 10u+t
so its (10u+t)-(10t+u)=18
which gives 9u-9t=18
3.5h+10=5.25h-11
21=1.75h
12=h
3.5(12)+10=5.25(12)-11
52=52
Answer:
A=Both distributions are nearly symmetric
Step-by-step explanation:
If you would like to know how many papers will be missing the name, you can calculate this using the following steps:
