Answer:
0.625
Step-by-step explanation:
Answer: x=2
Step-by-step explanation:Algebraically solve this equation. First subtract x from 2x which gets you just x. then subract 3 from 4 which gets you 1. Then subract 1 from 3 which gets you to the equation x=2. You can plug it in and check
2(2)-3-2+4=3 which is 4-3-2+4=3 which is -1+4=3 which is 3=3 which is correct.
Hope this helps :)

Total for all triangles=180
Step-by-step explanation:
In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:
3y+2y+y=180
6y=180
y=30
It's fairly easy to solve from there. Just more multiplying and subtracting.
