Sam is an accountant. he finds that he spends two-fifths of his work day answering emails. if he kept 3.6 hours answering emails yesterday, how many hours did he work?

Let the total hours that Sam has in a workday be depicted by the letter x.

Sam finds that he spends two-fifths of his work day answering emails which amounts to 3.6 hours.

If we write the above information mathematically, we will get:

We will now isolate x. Thus we have:

hours

Thus Sam has a typical workday of 9 hours. Out of this he spends 3.6 hours writing emails. Therefore, the number of hours Sam worked is:

9-3.6= 5.4 hours.

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
