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:

\frac{2}{5}x=3.6

We will now isolate x. Thus we have:

x=\frac{3.6\times 5}{2}=9 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.

Divide it into one piece so 3.6 / 2 = 1.8 then times that by the number of pieces you want so 3.6 / 2 * 5 = 9

-6(y+15)=-3y+6<br> what value of y makes the equation true
AlladinOne [14]

Answer:

y = -32

Step-by-step explanation:

-6(y+15)=-3y+6

Distribute

-6y - 90 = -3y +6

Add 6y to each side

-6y -90+6y = -3y+6y +6

-90 = 3y+6

Subtract 6 from each side

-90 -6 = 3y +6-6

-96 = 3y

Divide by 3

-96/3 = 3y/3

-32 = y

Which interval notation represents the set of all numbers less than or equal to -6 or greater than or equal to -2
Alik [6]

Answer: 1≤x<12

Step-by-step explanation:

The values that are greater than or equal 1 but less than 12 are values ranging from 1 to 11 i.e {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}. Note that 1 is included because the number is greater than or equal to 1 (1 included) and less than 12(12 not included).

x≥1 and x< 12

if x≥1, it means 1≤x

combining both inequality

1≤x and x<12

1≤x<12

The interval notation that represent the set S =  {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} will be given as S = {x: 1≤x<12}
