Answer:
4/5
Step-by-step explanation:
1/2=5/10
5/10+3/10=8/10
simplified or 8/10 divided by 2 =4/5 and u cant simplify it anymore
The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides

Dividing both sides by 3

The car was towed for 48 miles.

Find the constant of variation
From the question, the variation is as follows



Convert variation to equation

Where k represents the constant of variation
Make k the subject of formula;
Multiply both sides by s * t


Divide both sides by p



Substitute the values of p, r, s and t in the above equation


Divide numerator and denominator by 6

Hence, the constant of variation is; 
The answer is Y = -1/2x + 60
