Answer: 160 miles.
Step-by-step explanation:
Equation = $142.40 = .24x + 104
Define Variable = x = number of miles driven
Solve Equation = Subtract 104 from each side:
38.40 = .24x
Divide both sides by .24:
160 = x
The van was driven 160 miles.
Answer:
step 3
Step-by-step explanation:
Answer:
value of x is 7
Step-by-step explanation:
from question
k+b=90
5x+15+40=90
5x=90-55
5x=35
hence, x=7
It just so happens that it's always the same y for each x, but it is only that one y. So this is a function; it's just an extremely boring function! ... So this is a relation, but it is not a function.
