Answer:
4x + 276
Step-by-step explanation:
Multiply 4 by 69 and x.
Answer:
x=29/2
Step-by-step explanation:
The two angles when added together need to equal 180 degrees:
-4x +5 + -13x +39 = 180
Simplify:
-17x + 44 = 180
Subtract 44 from each side:
-17x = 136
Divide both sides by -17:
x = 136 / -17
x = -8
20/22
Divide both numbers by 2.
10/11.
This is the simplest form.
