Answer:
312
Step-by-step explanation:
25+.15x=71.80
-25 -25
.15x=46.8
46.8/.15
x=312
I think its about 62 hours because you multiply the 185 days by 20 minutes and get 3,700 so you divide that by 60 and get 61.6666667. so the answer is 62 hours?

Step-by-step explanation:
So we go backwards, since we have x= 1/2 , 7

Now we have to foil to get the quadratic

We must simplify the terms

Our final result comes out to be




Therefore, the value of x is 7.375.


Hence verifed.
