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.

13x−6y=22 x=y+6 ​ whats the answer
Vikentia [17]

Answer:

x = -2 y = -8

Step-by-step explanation:

13x - 6y = 22

x - y = 6

6(x-y) = 6*6

6x - 6y = 36

subtract both the equations

13x - 6x -6y + 6y = -14

7x = -14

x = -2

13*-2 -6y=22

-26 -6y=22

-6y = 48

y = -8

answer: x = -2  y = -8
