You can simplify a factor 2 in the first fraction:
![\dfrac{2e}{2n} = \dfrac{e}{n}](https://tex.z-dn.net/?f=%5Cdfrac%7B2e%7D%7B2n%7D%20%3D%20%5Cdfrac%7Be%7D%7Bn%7D)
And you can ignore the ones in the second:
![\dfrac{1w}{1n} = \dfrac{w}{n}](https://tex.z-dn.net/?f=%5Cdfrac%7B1w%7D%7B1n%7D%20%3D%20%5Cdfrac%7Bw%7D%7Bn%7D)
If two fractions have the same denominator, you can sum the numerators:
![\dfrac{e}{n}+\dfrac{w}{n} = \dfrac{e+w}{n}](https://tex.z-dn.net/?f=%5Cdfrac%7Be%7D%7Bn%7D%2B%5Cdfrac%7Bw%7D%7Bn%7D%20%3D%20%5Cdfrac%7Be%2Bw%7D%7Bn%7D)
Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)
The -4 would be your y-intercept and the 2x would be your slope. So you would put a mark on the-4 on the y axis and go up 2 and to the right 1 to plot your line. The second one would put your starting dot on the (0,0) and go up 2 and to the right 1 to get your line. Because you would look at the 2x as 2/1x.

Answer:
30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
410216 is the ans
I hope it helps u !
