X = (w + y + z) / 4....multiply both sides by 4, cancelling the 4 on the right
4x = w + y + z ....subtract w and subtract z
4x - w - z = y....answer is A
-1/3 is the slope of the line perpendicular to k
18 is the answer to the question 5 divided by 8 is .625 so you have 17.625 round to the nearest whole number gives you 18 lol. Heyy and be a true one and mark me the brainlest answer :)
Answer:
887 and 792 km per hour
Step-by-step explanation:
Lets call the first plane A and the second B
we know that: a=b+95
We can say that 3358=2b+(2b+190)<=A
When solved, we get 3168=4b
b=792 km per hour.
Go back to step two. A=b+95, so A=792+95=887 km per hour
The two planes rates are 887 km per hour and 792 km per hour.
