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.
Opposite angles are equal so the equation is
x + 71 = 108 (A)
Answer:
6x - 4
Step-by-step explanation:
f(x) + g(x)
= 4x + 8 + 2x - 12 ← collect liketerms
= 6x - 4
Answer:
Ba0.12 if b have x plus 5.10 need to be A
Answer:
Step-by-step explanation:
Yay graphs!!!!!!
Okay so as you should know, the structure of a linear equation is y = mx + b.
B is the y-intercept
so the first thing to do is mark the coordinates (0,1) as the y-intercept
Now the slope is 1/4 x
this is also known as rise/run
A simpler way to do that is from (0,1) move up 1 and over four and place a point there
The coordinate should be (4,1)
Then draw a line through the two points
