max2010maxim [7]
Gross pay = $2,759.00
Total deductions = 7.65%+12%+7% = 26.65% = 0.2665

If point C is inside AvB, then __+m CvB= m AvB
adelina 88 [10]

Answer: OPTION A

Step-by-step explanation:

It is important to remember the "Angle Addition Postulate" in order to solve this exercise.

You have this larger angle:

 \angle AVB

According to the "Angle Addition Postulate", if the point "C"  is in the interior of \angle AVB, then the measure of this angle can be obtained by adding the angle \angle AVC and the angle \angle CVB.

You can observe in the figure that:

 m\angle AVC=39\°\\\\\mangle CVB=23\°

Then you get that:

m\angle AVC+m\angle CVB=m\angle AVB\\\\39\°+23\°=62\°

Therefore, the correct answer is Option A.

2.) Bob has two weekend jobs. Last weekend he made a total of $77 after
aalyn [17]

Answer:

Step-by-step explanation:

x= money earned per hour working as a cashier.

y=money earned per hour working delivering newspapers.

We propose the following system of equations:

5x + 4y =77

6x + 3y=78

We solve the system by reduction method:

-6*(5x+4y=77) ⇒  -30x-24y=-462

5*(6x+3y=78)⇒     30x+15y=390

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

                                     -9y=-72  ⇒   y=-72 /-9=8

Now, we get the value of "x" replacing the value of "y" by "8" in any part of the equation above.

5x + 4(8)=77

5x+32=77

5x=77-32

5x=45

x=45/5=9

therefore;  

money earned per hour working as a cashier= $9/ hour

money earned per hour working delivering newspapers=$8/hour
