I think you mean exclamatory, which means a remark one expressing surprise or pain.
30N=2-8N
Subtract 8N from 30N and you get 22N.
22N=2
Divide by 22 on both sides. You get N=2/22
So your answer is N=1/11
Answer:
D) 7.01
Step-by-step explanation:
The rates of doing work, in terms of jobs per hour, will add when the two painters are working together. If A represents Alberto's time to do the job alone, we have ...
1/4.12 = 1/10 + 1/A
(Jobs per hour is the inverse of hours per job.)

It takes Alberto 7.01 hours to do the job alone.
