Molly's equation
15x + 10 = 100
-10 -10
15x=90
/15 /15
x=6
Maddie's equation
15x - 10 = 100
+10 +10
15x=110
/15 /15
x=7 1/3
MADDIE IS RIGHT
this is because she said 7 ans=d you cannot buy 1/3 of a shirt.

Answer:
5
Step-by-step explanation:
1:equilateral
2:isosceles
3:scalene
4:right
5:acute
6:obtuse
So we just need to plug in our values and solve
![v = 20 \sqrt{273 + t}](https://tex.z-dn.net/?f=v%20%3D%2020%20%5Csqrt%7B273%20%2B%20t%7D%20)
we are given v is 369 so we have
![369 = 20 \sqrt{273 + x}](https://tex.z-dn.net/?f=369%20%3D%2020%20%5Csqrt%7B273%20%2B%20x%7D%20)
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
![369 = 20 \sqrt{273 + x} \\ 18.45 = \sqrt{273 + x} \\ 340.40 = 273 + x \\ x = 67.4](https://tex.z-dn.net/?f=369%20%3D%2020%20%5Csqrt%7B273%20%2B%20x%7D%20%20%5C%5C%2018.45%20%3D%20%20%5Csqrt%7B273%20%2B%20x%7D%20%20%5C%5C%20340.40%20%3D%20273%20%2B%20x%20%5C%5C%20x%20%3D%2067.4)
so a temp of about 67 degrees C
Answer:
i)32C16
ii)1185408
<em><u>Explanation</u></em><em><u>:</u></em>
i)Total number of selected/eligible is 7+9+8+8=32
Total ways of selecting dance committee of 16 is
<em><u>3</u></em><em><u>2</u></em><em><u>C</u></em><em><u>1</u></em><em><u>6</u></em>
ii)Total ways of selecting 3 seniors from 8 is 8C3
and Total ways of selecting 6 juniors from 8 is 8C6
ways of selecting 2 sopho from 9 is 9C2
ways of selecting 5 freshman from 7 is 7C5
now, total way of selection come to be
8C3×8C6×9C2×7C5
=56×28×36×21
=1185408
