Answer:
x = 37
Step-by-step explanation:
A straight angle is 180 degrees. That means ∠DFG & ∠EFG have to add together to be 180.
2x + 6 + 3x - 11 = 180 Combine like terms
5x - 5 = 180 Add 5 to both sides
5x = 185 Divide by 5
x = 37
∠DFG = 80°
∠EFG = 100°
Answer: m = 1/2
Step-by-step explanation: To find the slope of the line, we would first put the equation in y = mx + b form to get y by itself on the left side.
So divide both sides by 2 to get y = 1/2x - 4.
Now the slope is the coefficient of the x term which is 1/2.
This is a positive slope.
Answer:
B. $42.60.
Step-by-step explanation:
On the first day price is 43.85 + 2.70 = $46.55
second day price is 46.55 + 2.70 = $49.25
For the next 2 days it goes down $1.10 so the price is $49.25 - 2.20=$47.05
On the last day it loses $4.45 so the final price is $47.05-4.45 = $42.60.
