325 - 7 = 318
318/6 = 53 people per bus
If B is a complement of A this means that the sum of the measures of A and B is 90 degrees.
mA + mB = 90
mB =90 - mA
mB = 90 - 40 = 50
Thus, the measure of angle B is 50 degrees.
If C is a supplement of B then, the sum of the measures of B and C is 180 degrees.
mC + mB = 180
mC = 180 - mB
mC = 180 - 50 = 130
Therefore, the measure of angle C is 130 degrees.

Answer:
x = 2
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-3(x - 1) = x - 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -3: -3x + 3 = x - 5
- Add 3x to both sides: 3 = 4x - 5
- Add 5 to both sides: 8 = 4x
- Divide 4 on both sides: 2 = x
- Rewrite: x = 2
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -3(2 - 1) = 2 - 5
- Subtract: -3(1) = -3
- Multiply: -3 = -3
Here we see that -3 does indeed equal -3.
∴ x = 2 is a solution of the equation.
Based on the table, Josie is paid $43.75 for 5 hours work. For 1 week's work, the pay will be for 40 hours, 8 times that amount, or
.. Josie's weekly pay = 8*43.75 = 350.00
Based on the graph, Salvador gets paid $15.00 for 2 hours work. For 1 week's work, the pay will be for 40 hours, 20 times that amount, or
.. Salvador's weekly pay = 20*15.00 = 300.00
Josie earns 350 -300 = 50 more each week than Salvador. For Josie to earn 1000 more, we can solve the equation
.. 50*weeks = 1000
.. weeks = 1000/50 = 20
It will take Josie 20 weeks to earn $1000 more than Salvador does in the same period.
