Answer: 35 additional teachers are needed
-------------------------------------------------
-------------------------------------------------
Explanation:
We have 2470 students and the ratio of students to teachers is 26:1. This means that for every teacher, there are 26 students. Put another way, we can set up this ratio
2470/x = 26/1
where x is the number of teachers. Cross multiply and solve for x
2470/x = 26/1
2470*1 = 26*x
2470 = 26x
26x = 2470
26x/26 = 2470/26
x = 95
So we have 95 teachers currently
-------------
Let y be the new number of teachers needed to bring the ratio down to 19:1
Using a similar idea as done above, we would have this ratio
2470/y = 19/1
Let's solve for y
2470/y = 19/1
2470*1 = 19*y
2470 = 19y
19y = 2470
19y/19 = 2470/19
y = 130
So we'll need 130 teachers to have the ratio be 19:1
The difference of the values is y - x = 130 - 95 = 35, which is the final answer. This is the additional amount of teachers needed.
I believe the correct answer is a hope this helps

idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want
Step-by-step explanation:
Let's solve for x.
6x+7y=13x
Step 1: Add -13x to both sides.
6x+7y+−13x=13x+−13x
−7x+7y=0
Step 2: Add -7y to both sides.
−7x+7y+−7y=0+−7y
−7x=−7y
Step 3: Divide both sides by -7.
−7x
−7
=
−7y
−7
x=y
