Answer:
20
Step-by-step explanation:
Let the number of sides be n
One exterior angle = 360/n
Exterior angle + interior angle = 180
Interior angle = 180 - Exterior angle
= 180 - 360/n
Sum of interior angle = n(180 - 360/n) = 3240
n(180 - 360/n) = 3240
180n - 360 = 3240
180n = 3240 - 360
= 3600
n = 3600/180
= 20
Answer:
=−6y−20
Step-by-step explanation:
Let's simplify step-by-step.
−13−2y−7−4y
=−13+−2y+−7+−4y
Combine Like Terms:
=−13+−2y+−7+−4y
=(−2y+−4y)+(−13+−7)
=−6y+−20
Answer:
I think the number of terms are 3
Answer:
Your answer would be A
Step-by-step explanation:
Okay, so. We know they lost 320 dollars but then they earned 126 dollars, profit means they earned it. So, we know it won't be B, because it does not shows they lost any money, it could be C, it could be A, but it is not D. So, then we look at A and C. We then notice 126 has a negative sign and A does not, we know that then it is going to be A. Also, if you need to know how much more money they are in debt. This is what you do.
-320 + 126 = -194
You would add the negative into the positive.
Hope this helps!
