Angle 1 and angle 5 are equal so you can set the equations equal to each other. 60 - 2x = 70 - 4x
60 + 2x = 70
2x = 10
x= 5
Its 58.9875 so about $59

Well, we know that 25% is also 1/4 and if we multiply $80.00 by 1/4 you get $20 so the answer is $20.
20 miles/2 hours = 10 miles/1 hour, therefore her average speed is 10mph
Answer:
<u>Linear</u>

Therefore y=-x is linear.


The degree of this equation is 2.
It is non-linear

is also linear.
