Calculate the pay for the following day of a
USPshnik [31]

Answer:  $122.50

<u>Step-by-step explanation:</u>

In          Out

8:00    12:00    = 4 hours

12:45    17:30   =<u> 4.75 hours   </u>

          Total        8.75 hours

8.75 hours x $14/hr = $122.50

Note: to subtract 12:45 from 17:30, borrow 1 hour from 17 and add 60 minutes to 30:

 17:30       →         16:90

- 12:45                -<u> 12:45 </u>

                            4: 45

4 hours 45 minutes = 4\frac{3}{4} = 4.75 hours

If f(x) = 3x - 2 and g(x) = 2x + 1, find (f - g)(x)
antiseptic1488 [7]

Answer:

A

Step-by-step explanation:

note that (f - g)(x) = f(x) - g(x)

f(x) - g(x)

= 3x - 2 - (2x + 1) ← distribute by - 1

= 3x - 2 - 2x - 1 ← collect like terms

= x - 3 → A

If K is the midpoint of JL, JK = 8x + 11 and KL = 14x – 1, find JL.​
masha68 [24]

Answer:

JL=54

Step-by-step explanation:

We are given that K is the midpoint of JL. Using this information, we want to find JL.

By the definition of midpoint, this means that:

JK=KL

Substitute them for their equations:

8x+11=14x-1

Solve for <em>x.</em> Subtract 8<em>x</em> from both sides:

11=6x-1

Add 1 to both sides:

6x=12

And divide both sides by 6. Hence:

x=2

JL is the sum of JK and KL. Hence:

JK+KL=JL

Since JK = KL, substitute either one for the other:

JK+(JK)=2JK=JL

Substitute JK for its equation:

2(8x+11)=JL

Since we know that <em>x</em> = 2:

2(8(2)+11)=2(16+11)=2(27)=54=JL

Thus:

JL=54
