Answer:
2l + 3 = 39
Step-by-step explanation:
Let l = Lindsay's age in years.
Carol's age is three more than two times Lindsay's age
Carol = 2l+3
Carol = 39
39 = 2l+3
X + 3 = 9-4
First simplify the right side.
9-4 = 5
Now you have x + 3 = 5
Now subtract 3 from both sides:
X = 2
Answer: x = 2
Answer:
Step-by-step explanation:
Step One
Find the exterior angle connected to the 93 degree angle. It is also a supplement to 93. Supplementary angles add to 180. Call the exterior angle y
93 + y = 180 Subtract 93 from both sides
y = 180 - 93
y = 87
Step two
Add all the exterior angles. They equal 360
x + 52 + 87 + x + 3 + 78 = 360 Combine the like terms
Step 3
Solve the equation
2x + 220 = 360 Subtract 220 from both sides
2x = 360 - 220
2x = 140 Divide by 2
x = 70
I don't see that anywhere, but I'm pretty sure I'm right.

Answer:
<h3>The slope is -1.</h3>
Step-by-step explanation:
To find an equation of the line that passes through the points, you have to use the slope formula.
Slope:
y2=3
y1=(-2)
x2=(-1)
x1=4
Solve.
3--2/-1-4=5/-5=-1
The slope is -1.
