Answer:
It would be C
Step-by-step explanation:
The fraction equal to 4/5 is 8/10 so closest to 8/10 is 8/11
The sum of the angles should be 180, so x+ (x+10) + (x+5) = 180. This simplifies to 3x + 15 = 180, so 3x = 165, so x=55.
Answer:
x = 2
Step-by-step explanation:
5x - 2 = 10 - x
<em>Add x to both sides</em>
6x - 2 = 10
<em>Add 2 to both sides</em>
6x = 12
<em>Divide both sides by 6</em>
x = 2
Answer:
x = 21
Step-by-step explanation:
the equation is 2x + 10 = 52
2x = 42
x = 21
