Answer:
$86.50
Step-by-step explanation:
Let b represent the bill before tax and tip. Then the total is ...
b + 0.05b + 0.15b = 103.80
b(1.20) = 103.80 . . . . . . . . . . collect terms
b = 103.80/1.20 = 86.50 . . . divide by the coefficient of b
The bill before tax and tip was $86.50.
for the table its 30 * the hours +20 for example 30(1)+20=50 or 30(4)+20=140. the total cost is 30 times the hours plus 20.
Answer:
y= -1/2 + 1
Step-by-step explanation:
It starts at +1 which is the B in y=mx+b. B is where a point touches the y-axis.

Answer:
z=-13
Step-by-step explanation:
LEAVE AN BRIANLEST!!!
We can't really do this you will have to use your ruler and draw lines on the points. Example: For number 4, draw lines at 4 vertically on the x-axis and join it with another line on the y-axis. Then you can tell the answer. Sorry! Best of luck!
