Answer:
w = 40 miles per hour
r = 300 miles per hour
Step-by-step explanation:
We add w with the wind and subtract w against the wind
r+w = 340 miles per hour
r - w = 260 miles per hour
Add the two equations together to eliminate w
r+w = 340 miles per hour
r - w = 260 miles per hour
----------------------------------------
2r = 600
Divide by 2
r = 300 miles per hour without the wind
Now find w
r+w = 340
300 + w = 340
Subtract 300
w = 340-300
w = 40 miles per hour
Answer:
x = 9 (see explanation)
Step-by-step explanation:
Alternate exterior angles are two angles that are congruent to each other:
1. Set the two angles equal to each other: 7x-4 = 6x+5
2. Combine like terms and solve for x: x = 9
