  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

-11w - 4 = 7

3w - 10

<u>Step 2: Solve for </u><em><u>w</u></em>

  1. [Addition Property of Equality] Add 4 on both sides:                                     -11w = 11
  2. [Division Property of Equality] Divide -11 on both sides:                                w = -1

<u>Step 3: Evaluate</u>

  1. Substitute in <em>w</em>:                                                                                                 3(-1) - 10
  2. Multiply:                                                                                                             -3 - 10
  3. Subtract:                                                                                                             -13

What is the true hourly wage of a job that pays 18 per hour and allows 20 hours of paid time off for every 500 hours worked?
Talja [164]
To solve for the true hourly wage simply add the 2 rates together.

20 dollars/500 hours = 2/50 = 0.04 dollars per hour.

The true rate would be $18.000 + $0.04 = $18.04 per hour.

Trigonometry (ASAP) (Urgent) ​
Olin [163]

Answer:

h = 1.403733341286

Step-by-step explanation:

17.

the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.

Then

\cos \theta =\frac{l-h}{l}

Then

l\cos \theta =l-h

Then

h=l-l\cos \theta

18.

For l = 6  and  θ = 40 :

h=l-l\cos \theta

  = 6-6cos(40)

  = 1.403733341286
