I'm not sure if those numbers are negatives or thats just a hyphen but:
N(-5/8)=-0.40
Division is always the opposite of multiplication
-0.40/(-5/8)=0.64
N=0.64
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:
UW=14
Step-by-step explanation:
First we know that UV+VW=UW, so:
4+x+10=2x+14
Solve for x first:
x+10=2x+10
10=x+10
x=0
Then, substitute the X
2(0+14)=14=UW
To check your answer, substitute and add UV and VW
4+(0)+10
14
