Answer:
$21.00
Step-by-step explanation:
1(x+3)+x=45
x+3+x=45
x+x=42
2x=42
x=21
Answer:
x = 24 degrees
Step-by-step explanation:
You need to know, that one line has a total of 180 degrees. So, first solve for y by subtracting 180 - 103. You get 77. So y is 77 degrees. Now add 77 + 79 to get 156. Now subtract 180 - 156 to solve for x. You get 24 degrees.

Answer:
Nicole drove 66 miles.
Step-by-step explanation:

Answer:

Step-by-step explanation:
First draw a line. I will put it in an attachment so you can see the line.
Now choose to points on the line to use the slope formula.
(0,15) and (3,13).
Slope formula: 
Plug in the information needed using the two points chosen.

The slope is
.
Now use point-slope formula.
Point-slope formula: y-y1=m(x-x1)
y-15=
(x-0)
y-15=
x-0
Subtract 15 from both sides.
y=
x-15
