Answer:
a) y = 0.55x + 75
b) $108
Step-by-step explanation:
a) to find the equation represent the sequence use the y=mx+b formula
y = total price
m = cost per mile
x = miles driven
b = flat fee
Therefore y = 0.55x+75
b) To figure out the cost of driving 60 miles you use the equation y = 0.55x + 75
y = 0.55 X 60 + 75
= 108
Therefore the cost of renting the truck and driving 60 miles is $108
Answer:
(6,-5)
Step-by-step explanation:
As the point is 4 units to the left of X=2, the reflection must be 4 units to the right of X=2
The answer is 104.
1/4 of 104 is 26, 104 - 26 = 78
78 - 7 = $71
Answer:
There were 26 students in his class and the teacher had 83 ml of the solution.
Step-by-step explanation:
Mr. Kohl has a "x" amount of solution, if he divides it by the number of students "n" he'll give each student 3 milliliters and have a left over of 5 milliliters. If the amount of solution Mr. Kohl had was "x + 21" then he'd be able to give each student 4 milliliters of the solution. From these informations we have:
x = 3*n + 5
(x + 21)/n = 4
x + 21 = 4*n
x = 4*n - 21
Now that we have two equations and two variables we can solve the system of equations, as seen bellow:
3*n + 5 = 4*n - 21
3*n - 4*n = -21 - 5
-n = -26
n = 26
x = 4*26 - 21 = 83 ml
There were 26 students in his class and the teacher had 83 ml of the solution.
