You need to find "two-fifths of 30." Of here means multiplication:
![\begin{aligned}\dfrac{2}{5}\cdot 30 &= \dfrac{2}{5}\cdot\dfrac{30}{1}\\[0.5em] &= \dfrac{60}{5}\\[0.5em] &= 12\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%2030%20%26%3D%20%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%5Cdfrac%7B30%7D%7B1%7D%5C%5C%5B0.5em%5D%20%26%3D%20%5Cdfrac%7B60%7D%7B5%7D%5C%5C%5B0.5em%5D%20%26%3D%2012%5Cend%7Baligned%7D)
There are 12 athletes in the club.
Work shown above! x = 117 degrees
(x - 10) × 2
You have to multiply it by 2 so that you get the area
You have to use the distance formula.
Answer: 66
<u>Step-by-step explanation:</u>
20 points per day is the rate, 100 points is the intial amount, and 1420 points is the total.
Use the formula: y = mx + b
- y is the total
- m is the rate
- b is the initial amount
1420 = 20x + 100 <em>plugged the values into the equation</em>
1320 = 20x <em>subtracted 100 from both sides</em>
66 = x <em>divided both sides by 20</em>
