Answer:
-35/3
Step-by-step explanation:
-2(3x-2) + 3x + 3 = 34
-6x-4+3x+3=34
-3x-1=34
-3x=35
x=-35/3
Example: Is (5,2) a solution to <span>2x + 5y = 20? Subst. 5 for x and 2 for y:
2(5) + 5(2) = 10 + 10 = 20 Yes, (5,2) is a solution.</span>
Answer:
It is the portion of the cost based on renting a car for d days
Step-by-step explanation:
Given:
Total cost = 15 + 18d
Total cost = fixed cost + variable cost
Fixed cost are cost that do not change.
Fixed cost = base rate = 15
Variable cost changes during production process. The variable cost in the above varies with the number of days (d)
Therefore, 18d is the portion of the cost based on renting a car for d days.
If you rent the car for 1 day
Total cost = 15 + 18d
= 15 + 18(1)
= 15 + 18
= 33
