3926/13 =302 but I'm not 100% sure where you went wrong do you have any work?
The answer is 9x+8. if you distripute the 2, you get 2x-6. if you distribute the 7, you get 7x+14. then you combine like terms ans get 9x+8
Given The equation -2x(-2.8)=24, we are trying to find the value of X.
The first step is to devide both sides by 2
·-x(-2.8)=12
The next step would be to distribute.
·2.8x=12
Next we devide both Sides By 2.8 to get our final answer
·X=4.28
Although your choice answers are unclear, the answer is X=4.
-I hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.
Answer: 20 mph
Explanation:
Speed is a physical quantity which is equal to the ratio between the distance covered (d) and the time taken (t):

In the first part of the problem, the plane flew a distance of d=400 mi in a time of t=2.5 h. The speed of the plane in this case was the difference between the proper speed of the plane, v, and the speed of the wind, w, since the plane flew opposite to the wind. So we can write:
(1)
During the return trip, the plane flew with a speed (v+w), since the wind was on the tail, and it took 2 hours to cover the same distance:
(2)
So we have two equations with two unknown variables. From (1), we get

Substituting into eq.(2)

So, the speed of the wind was 20 mph.
