<span>2x + 8 = 6 - x
2x + x = 6 - 8
3x = -2
x = -2/3

The answer is 30
Explanation:
So all of the angles in a triangle add up to 180 degrees and so if you split the triangle into separate triangles then you can add up the angles that are known and subtract from 180 to get the size of the missing angle e.g 90 + 56 = 146, 180 -146 = 34 for the other triangle 90 + 26 = 116, 180 - 116 = 64 and so 64 - 34 = 30
It would be 4.8333333333.
The three repeats here.
-8n+4(1+5n)=-6n-14
-8n+4+20n=-6n-14
12n+4=-6n-14
12n+6n=-14-4
18n=-18
n=-18/18
n=-1
Answer:
x=3.5
Step-by-step explanation:
MN is divided in half because of MO. BN would equal 6, too. In all, LN should equal 12. So, your equation would be:
2x+5=12
Solve this equation:
2x=12-5
2x=7
x=3.5
