Answer:
(0,-5)
Step-by-step explanation:
You just have to find the middle of each one
From -8 to 8 there are 16 numbers so you divide 16 by 2 which would be 8 and add that to -8 giving you 0
From -10 to 0 there are 10 numbers divided by 2 is 5 so you add 5 to -10 giving you -5
This makes your midpoint (0,-5)
Answer:
Step-by-step explanation: First you would do this 1260.90 divided by 6 = 210. So then you would multiply 210 x 2 = 420. $420 is how much the people who are staying for 6 days. Then since we know it’s $210 per day, we would subtract $420 from 1260.90 and we would get 840.90. Divide that by 6 and get 140. 140 is how much those two people are paying for 2 nights.
