Step-by-step explanation:
1. Distribute the -2. multiply-2 with 5x and 8. it will be -10x-16=14+6x. For me, i make small numbers negative or positive than big ones. Add 16 to both sides. it will be -10x=30+6x. Subtract 6x. -10x-6x=-16x. Divide both sides by 16. x=30/16= 1 and 14/16
Answer:
5x + (x+12) = 90
x = 13
m∡1 = 5(13) = 65°
m∡2 = 13 + 12 = 25°
Step-by-step explanation:
6x + 12 = 90
6x = 78
x = 13
Answer:
a. pi
Step-by-step explanation:
Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20
---- ------
4 4
n = 5
The x value when everything is solved or when the all of the x's are combined?
