Answer:
x = -6
Step-by-step explanation:
Maybe this means you want to solve ...
-3x -8 = 10
-3x = 18 . . . . . add 8 to both sides
x = -6 . . . . . . . divide both sides by -3
Answer:
1. 90
2.60
3.30
4. 40
5. 80
6. 60
7. 30
8. 30
9. 120
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.
Write an equation
10 + 3x = 15 +2x
-2x -2x
-----------------------
10 + x (1x) = 15
-10 -10
----------------------
x = 5
cost= 25 (10 + 15)
Pretty sure is 63 degrees since the one next to it is exactly the same and its 63 degrees
Dat be called common difference represented by d in the equation
