Answer:

C

Step-by-step explanation:

First you distribute and multiply both 4x and -5 by 6. This gives you the following equation:

24x-30=42

Next, you add 30 to both sides, giving you:

24x=72

Finally, you divide it all by 24, leaving you with

The total cost of hiring paul the plumber is a function of the required number of hours needed to complete the repair. Paul char
DiKsa [7]

Paul surely charges 75 dollars, and then he adds 40 dollars per hours. This means that the expression for the money he asks is

m = 75+40h

where m is the amount of money and h is the number of hours.

Since h can be at most 8, this is the case that generates the highest money, so if we plug h=8 we have

m = 75+40\cdot 8 = 75 + 320 = 395

Answer:

118.625

Step-by-step explanation:

Lets clear this up.

M = $65.

6 months = 182.5 days

We may turn 65 into a decimal for a more exact answer.

<h3>65 = 0.65 (changing it to a decimal does not change the value.)</h3>

Now we can do

182.5 x 0.65

= 118.625.

For your homework you could say.

"6 months is 182.5 days, we would need to change 65 into a decimal, which is 0.65 to get a more exact answer. 182.5 x 0.65 = 118.625. Sally will be paid 118.625 in 6 months."
