Answer:
The answer is 8
- 3 + 2 - =<u> 4 </u> + <u>2 </u> .
Step-by-step explanation:
Given:
8x - 3x + 2 -x = __ x + __
Now, to write a number in each blank to complete each equation so that it has the requested number of solutions.
So, to solve the equation:
So, we add the variables:
And, then subtract it:
Thus, it remains:
.
So the complete equation is:
8 - 3 + 2 - =<u> 4 </u> + <u>2 </u>
Therefore, the answer is 8 - 3 + 2 - =<u> 4 </u> + <u>2 </u> .

Answer:
Airspeed in still air: 140 mph
Step-by-step explanation:
Let s represent the speed in still air. Recognize that the distance traveled is the same in either direction.
Also note that SF is north of LA.
Distance to SF from LA = Distance to LA from SF
(s-20)(mph)(4 hr) = (s+20)(mph)(3 hr)
Then:
4s - 80 = 3s + 60 => s = 60 + 80 + 140 (mph)
The airspeed of the plane was 140 mph in still air. With a tail wind, the plane is faster; with a headwind, slower.
