For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees. So, we have:
We add similar terms:
Answer:
Option D
The items below show the complete steps as to how this is being answered.
1. 3x - 4 = 14 >>>> Given
2. 3x - 4 + 4 = 14 + 4 >>>
Step number 2 above is an addition property of equality. Both sides of the equation are added with 4.
3. Simplifying >>>
3x = 18
4. 3x/3 = 18/3 >>>> Division property of equality
5. >>>> Simplifying,
x = 6
Hence, the order of the choices as answers is C, E, B, A, D.
Answer:
x=10.5
Step-by-step explanation:
40x-120=24x-48
40x-168=24x
16x-168=0
16x=168
x=10.5
Have a great day!
