Let t be the number of tolls they crossed.
Amount they spent at each toll = $1.75.
Amount they spent at gas station = $28.
Let C be the total amount they spent on gas and tolls.
If they crossed 1 toll, then
C = 28 + 1.75(1).
If they crossed 3 tolls, then,
C = 28 + 1.75(3)
If they crossed t tolls, then,
C = 28 + 1.75t
Here, the terms are 28 and 1.75t and the factors are 1.75 and t.
Answer:
r = -3
Step-by-step explanation:
Simplifying
5r + 15 = 0
Reorder the terms:
15 + 5r = 0
Solving
15 + 5r = 0
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5r = 0 + -15
Combine like terms: 15 + -15 = 0
0 + 5r = 0 + -15
5r = 0 + -15
Combine like terms: 0 + -15 = -15
5r = -15
Divide each side by '5'.
r = -3
Simplifying
r = -3
Answer: R would equal -3
Step-by-step explanation:
5 x -3 = -15
-15 + 15 = 0
