1. We want to add all alike terms and follow GEMDAS as well. Addition first 2x+3x=5x ,then -x(which is equal to -1x) + 10x = 9x. Now we add 5x + 9x = 14x.
Right now the equation looks like:
14x + 14 = -42
2. Now we process the equation,
Subtract 14 from the left side, but what u do to one side u do to the other so now the equation looks like:
14x = -56
3. Now we are almost finished last step.
14x changes to x and we divide -56 by 14 which equals -4. The answer is
X = -4
Ps. I spent way too long writing this answer
Answer:
Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.
Step-by-step explanation:
Since the Gotemba walking trail up Mount Fuji is about 9km long, and walkers need to return from the 18km walk by 8pm, if Toshi estimates that he can walk up the mountain at 1.5km / h on average, and down at twice that speed , these speeds taking into account meal breaks and rest times, to determine what is the latest time he can begin his walk so that he can return by 8pm the following calculation must be performed:
Climb: 1.5 km / h
Descent: 2 x 1.5 km / h = 3 km / h
Climb: 9 km / 1.5 km / h = 6 hours
Descent: 9km / 3 km / h = 3 hours
Total: 9 hours
8 PM = 20:00
20:00 - 09:00 = 11:00
Thus, Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.
Because the two angles on the right add to 180 degrees, we can create this system:
![(2x + 25) + y = 180](https://tex.z-dn.net/?f=%282x%20%2B%2025%29%20%2B%20y%20%3D%20180)
We can also prove that
![3x = 2x + 25](https://tex.z-dn.net/?f=3x%20%3D%202x%20%2B%2025)
, which, when solved, shows that
![x = 25](https://tex.z-dn.net/?f=x%20%3D%2025)
.
When plugged in to the original equation, we find that y = 105 degrees.

Answer:
= 14q
Step-by-step explanation:
21q - 7q
= 14q
(3q - p) (7)
= 21q - 7q
= 14q
