Answer:
x=-4
Step-by-step explanation:
2(|x+4|+3)=6
take out absolute value
2(x+4+3)=6
remove parrenthesis
2x+8+6=6
Simplify
2x+14=6
-14 -14
2x=-8
x=-4
Hope this helps!!!!!
Px + qy = r
2px - qy = 2r
----------------add
3px = 3r
x = 3r/3p
x = r/p
A is independent while b is dependent.
This is because b is equal to a decreased by 2. Anytime a changes, then b does as well. B can only change in accordance with a.
The return trip was 21.2 hours long.
Step-by-step explanation:
Given,
Speed of plane from US = 212 mph
Speed of plane on return trip = 232 mph
Let,
x be the time taken on return trip.
Time taken from US = x+2
We know that;
Distance = Speed * Time
Distance of plane from US = 212(x+2) = 212x+424
Distance on return trip = 232x
As the distance will be same, therefore,

Dividing both sides by 20

The return trip was 21.2 hours long.
