Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or 
In this problem
Let
x------> the number of gallons
y------> the number of miles
the relationship between the number of miles and the gallons of gas represent a linear direct variation
The constant of proportionality k is equal to the slope m

therefore
the equation of the linear equation

Use the distributive property and multiply everything in the parentheses by 14.
Leaving you with.. (70 - 3.5 x 350) + 2 / 4 x 1.
Then reduce the parentheses.
Leaving you with.. ( -1155) + 2 / 4 x 1
Then divide 2 by four.
Leaving you with.. (-1155) + .5
