Answer:
(-8,0)
Step-by-step explanation:
Since the x and y of the mid point is less than the end point the line segment is going down. the difference between the end and mid point is 6 for x and 3 for y. -2-6 is -8 and 3-3 is obvi 0
I cannot see the numbers but i am guessing it is 2 since its in the negative region
When the hotel manager rides down 2 floors from 19 floor, it means he stops at floor 17, the floor he rides down as negative integer = -2
then he rides down 3 floors and it means he stops at floor 14, so the number of floors he rides down from there = -3
then he rides to the first floor as there is no number 13 floor it means he rides down 12 floor = -12
the <span>addition expression using negative integers to show the number of total floors the hotel manager rode down the elevator = -2 + (-3) + (-12) = -17</span>
35-7 which would equal 28, but that answer wouldn't be exactly correct, as this isn't in correct formation. An equation would be 2x + 7 = 35.
35-7= 28 divided by 2(2x) would equal 14
So Mary is 14 and her sister is 21.
21 + 14 equals 35
