Mason owns a trucking company. For every truck that goes out, Mason must pay the driver $13 per hour of driving and also has an expense of $1 per mile driven for gas and maintenance. On one particular day, the driver drove an average of 30 miles per hour and Mason's total expenses for the driver, gas and truck maintenance were $258. Write a system of equations that could be used to determine the number of hours the driver worked and the number of miles the truck drove. Define the variables that you use to write the system.

Which postulate proves that the triangles below are similar?
SSS
AA
SAS
These triangles are not similar
Answer:
AA~
Step-by-step explanation:
These triangles are similar but not congruent. One triangle is bigger than the other, meaning none of the side lengths are the same. On the triangles, two angles are given, a 53 degree and a 90 meaning that you would us the AA rule to determine if they are similar. Which they are.
The two triangles are similar triangles using AA postulate.
What are Similar Figures?Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. It is denoted by the symbol "~".
Given one of the angles in both the triangles is equal to 53°, the other angle is 90°, which are also the vertical angles to each other. As shown below.
Hence, the two triangles are similar triangles using AA postulate.

Find the value of x and the value of y.
A. x = 130, y = 50
B. x = 135, y = 45
C. x = 140, y = 40
D. x = 145, y = 35
Answer:
B. x = 135, y = 45Step-by-step explanation:
x° + y° = 180° {suplementary angles}
x° = 3y° {corresponding angles by parallel lines}
So:
3y° + y° = 180°
4y° = 180°
y° = 45°
y = 45
x° = 3×45° = 135°
x = 135
Elena has $5 and sells pens for $1.50 each. She wants to

5.02 Which equation does the graph below represents?
1. y = -1/2x
2. y = -2x
3. y = 1/2x
4. y = 2x
Answer:
2. y= -2x
Step-by-step explanation:
When the line is on an exact point like it is on (-4, 8), we can simplify it by going rise/run
Rise is the same as y (8), and your run is x (-4)
When you divide 8/-4, your answer will be -2
Therefore, the answer is y= -2x

500.
Solution: 210 is 42% of X
Equation: Y = P% * X
Solving our equation for X
X = Y/P%
X = 210/42%
Converting percent to decimal:
p = 42%/100 = 0.42
X = 210/0.42
X = 500
