Sara's bank account has a debt of $25. Sofia's bank account has a balance of $7. Who has more money in their bank account? Write an inequality explaining the answer.
Answer: D -2,0 and (5,0)
Step-by-step explanation:
Add 5 to the side with -5 so it cancels out the -5. Move the positive 5 to the side with 4. Your equation is h = 4+5. Take 4+5 to get 9 and your equation is h=9. :)
Answer: 18 sides
Solution:
Formula for calculating no. of sides of regular polygon:-
180 x n-2/n = interior angle
180 x n-2/n = 160
18 x n-2/n = 16
9 x n-2/n = 8
9n - 18 = 8n
n = 18
