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.
I would say C instead of A but I am not so sure.
X=2
You first solve for y on the other equation 6x+3y=15 which will be: y=5-2x
Then you make it one equation: 3x-5=5-2x
Third step is add the -2x with the 3x which is will be 5x.
Fourth: your new equation will be 5x-5=5
Next u would add 5 plus which is 10
Lastly your new equation is 5x=10
I honestly hope this helps !!!!
