Answer:

2 hours

Step-by-step explanation:

Given

Contractor: 81x + 108

Electronic\ Store: 103x + 64

Required

Determine the hours when the charges are the same

To do this, we simply equate both expressions:

Contractor = Electronic\ Store

81x + 108 = 103x + 64

Collect Like Terms

81x - 103x = 64 - 108

-22x = -44

Divide both sides by -22

x =2

Solve for n<br><br> -19=-8+n
laila [671]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{n = -11}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{-19 = -8 + n}

Find:  \textsf{Solve for n}

Solution: In order to solve for n we need to add 8 to both sides which would cancel -8 on the right side and isolate n giving us the value of n.

<u>Add 8 to both sides</u>

  • \textsf{-19 + 8 = -8 + 8 + n}
  • \textsf{-19 + 8 = n}
  • \textsf{-11 = n}

Therefore, the final answer would be that n is equal to -11.

Find the percent of increase or decrease from the first number to the second number. 140 to 84
tresset_1 [31]
We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:

140/84=100/x (this equation is basically saying if 140 is 100(%) what would 84 be?)

solving for x here gives us x = (84 X 100)/140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.

Let me know if I can clear anything else up.
