31.5 hours
It is not 4.5 x 14 because he works 7 days over the 2 week schedule

<em>Identify</em>
3 + 8x - 2y - x + 1 + 4y
<u>Step 2: Simplify</u>
- Combine like terms (x): 7x + 3 - 2y + 1 + 4y
- Combine like terms (y): 7x + 2y + 3 + 1
- Combine like terms: 7x + 2y + 4
72 I think I hope its right I had to write all over my paper lol
Answer:
B) 36/(y+4)
Step-by-step explanation:
Use the process of elimination.
A cannot work because we are changing the operation. Instead of dividing thirty-six by the sum of four and a number, we are dividing thirty-six by four, then adding the unknown number. This is not the same as the original expression, so we know it is not this.
Next, check C. C doesn't seem right either. Remember that, unlike multiplication and addition, you cannot flip the order in which the operation is being done and still get the same answer. C says four plus a number divided by thirty-six, which is entirely different from our original expression. So the answer is not C.
And finally, check D. D doesn't work either. With D, we are dividing thirty-six by a number, then adding it to thirty-six divided by four. This is not the same as our original expression, so D isn't it.
That leaves us with B. Does it work? Yes, because changing the y and the four still will give the same thing. And yes, because 36 is being divided by the sum of that number and four. So it is our answer.
