Y=x-3 it's one of many equations
Answer:
The answer is A.
Step-by-step explanation:
1 plus 2x (276-5y) + 69= A.
8/9 is just under 1 and 4/7 is just over 1/2
Estimating the sum would be 1 1/2
21, A 13, B You're welcome!
Every polygon has a sum of exterior angles equal to 360° (This doesn’t apply to interior angles, though.)
If you have exterior angles that are 40° each, then you can see how many times it goes into 360° to find your number of sides.
360° / 40° = 9 sides
Hope this helps!
