Angle 3 is 65 degrees. solve for x if angle 5 is equal to 5x.

Answers

Answer:

X=23

Step-by-step explanation:

If angle 3 measures 65 degrees the so does angle 2, 7 and 6. By the definition of parallel lines. Then by the definition of supplementary lines angle 5+ angle 7=180 degrees, so 5x+65=180 => 5x=115 => [tex]\frac{5x}{5}[/tex]=[tex]\frac{115}{5}[/tex] => x=23.

Phil earns $9.50 an hour and has deductions of $55 per week. If Phil worked 45 hours per week, what will his net pay be for one year?

Answers

Answer:

427.5 - 55 = 372.5 x 52 = 19370

his net pay will be 19370 if I am correct.

Answer:

$19370

Step-by-step explanation:

We need to find out how many hours Phil works in a year.

45h/week

There are 52 weeks in a year.

[tex]45 * 52 = 2340[/tex]

Now that we know that Phil works 2340 hours a year, we can solve for how much Phil earns in a year.

[tex]2340*9.5=22230[/tex]

Phil earns $22230 a year.

If deductions of $55 occur weekly, then we can do the following equations to solve for the value of Phil's net pay.

1. [tex]55*52=2860[/tex]

2. [tex]22230 - 2860 = x[/tex]

3. Solve for x

4. [tex]22230 - 2860 = 19370\\[/tex]

x = 19370

Phil's net pay is $19370 a year.
