the daily cost of renting a car is $25 plus $0.40 per mile traveled. If Paul paid $143.40 for a day's rental how many mile did h

Mama L [17]

Answer:

295 mi

Step-by-step explanation:

we can write this as an equation. the base fee, with no miles traveled is 25. this will be our y intercept, or b in the equation y = mx + b

our slope is .4

for every 1 mile increase for x, our y increases by .4

so:

y = .4x + 25

set this equal to 143.40

143.40 = .4x + 25

x = 295 mi

Transform the equation to isolate x: ax = bx + 1. How is

shepuryov [24]

Answer:

$x=\frac{1}{a-b}$

The value of x is inversely proportional to the difference of a and b.

Step-by-step explanation:

The given expression is $ax-bx+1$

We factor the left hand side to get:

$(a-b)x=1$

We divide both sides by: a-b

$x=\frac{1}{a-b}$

Observe that the difference of a and b is in the denominator.

The whole is of the form: $x\propto \frac{1}{a-b}$

The value of x is inversely proportional to the difference of a and b.
