Add them all up to get it
Hey there! :)
Answer:
(3.5, -1).
Step-by-step explanation:
Use the midpoint formula to solve this problem:

Plug in the coordinates given:

Simplify:

Therefore, the coordinates of the mid-point are:
(3.5, -1).
Part A: 7/10 because .7 represents 70/100 of a whole, or 7/10.
Part B: I think 1 and 89/100 because 89/100 represents that fraction
These are my answers, so I may be wrong.
Hope I helped, and good luck!
You can calculate them out and check which one is the most accurate
so if one of the choices was 1/3 of 50, then you would do:
1/3 in the calculator (should be 0.333...) times 50
And you can compare it with the EXACT number, which is:
0.25*53=13.25
This way you can test all the options
<span>8 + 5n = -72
5n = -72 - 8
5n = - 80
n = -80/5
n = -16</span>
