Answer:
Step-by-step explanation:
Given coordinates are (6,-3) and (-5,-4).
![\sf Slope = \frac{y2-y1}{x2-x1}\\\\Slope = \frac{-4+3}{-5-6} \\\\Slope = \frac{-1}{-11} \\\\Slope = \frac{1}{11} \\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20Slope%20%3D%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-4%2B3%7D%7B-5-6%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-1%7D%7B-11%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B1%7D%7B11%7D%20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

Answer:
Step-by-step explanation:
the way to find how many participanted in the class voted, you need to look at the percentages and the number of students that voted for Vicky.
50% of students voted for Vicky and the question later explained that the total of the 50% was 30 students. This mean we know half of the student that participated. To find the total amount of students to make 100%, you need to multiple 30 by 2. which is 60.
Now that we know there were 60 students in total, we can find how many participated by using Iverson's percentage.
this is the formula that can help with any percentage math problem:
The percentage of something ÷ 100% = the number you are looking for ÷ the total
in our case:
40÷100 = x (because it is the unknown term)÷60
from here you cross multiple getting
2400÷100x
which equals
24
now we have to add Vicky's and Iverson's voter
24 + 30= 54
60-54=6
6 students did not participate
It should be 25 or 20 because the way the problem is set up you should already have your answer of 2020
Step-by-step explanation:
3x+2x+10+2x+5+2x-15 = 360
9x+15-15=360
9x=360
x=40.
- 3x=3×40=120°
- 2x+5=2×40+5=80+5=85°
- 2x+10=2×40+10=80+10=90°
- 2x-15=2×40-15=80-15=65°.
hope this helps you.
