Answer:
There were 60 teachers.
Step-by-step explanation:
☆We can use proportion to solve this!
[tex] \frac{3 \: teachers}{125 \: pupils} = \frac{x}{2500 \: pupils} \\ \\ \frac{125x}{125} = \frac{7500}{125} \\ \\ x = 60[/tex]

The triangle is rotated 90° clockwise around the point (0,0). What will be the coordinates of the image of point L after the rotation?
Answer:
B
Step-by-step explanation:
You see the long side is right on the x axis so the L point will be the same length from itd rotation. Its rotation will have the long side laying along the Y axis and making it (2, 6)

Factor completely 5x2 − 5x − 100.
Answer:
5(x - 5)(x + 4)
Step-by-step explanation:
Given
5x² - 5x - 100 ← factor out 5 from each term
= 5(x² - x - 20) ← factor the quadratic
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)
The factors are - 5 and + 4, since
- 5 × 4 = - 20 and - 5 + 4 = - 1, then
x² - x - 20 = (x - 5)(x + 4) and
5x² - 5x - 100 = 5(x - 5)(x + 4)
Answer:
Step-by-step explanation:
here you go mate
step 1
5x2 − 5x − 100 equation
step 2
5x2 − 5x − 100 factor
5x^2 - 5x - 100 = 5
answer
5(x+4)(x-5)

Step-by-step explanation:
square root of 9 multiplied by square root of 180
Answer:
18√5
Step-by-step explanation:
√9×√180
from √9 we get 3 cause 3² is 9.
from 180 we get 6√5 because √36×5 is √180.
we took 36 out because it gives us a whole number if we square root it.
So √36×5 is 6√5 , because the square root of 36 is 6
then we multiply 3 and 6√5.
3×6 is 18 so we put 18 and put the √5 behind it.

SYSTEMS OF EQUATIONS- How many solutions?
Sy = 5x + 12
y = 5x + 18
O one solution
O no solution
O many solutions
Answer:
No solutions
Step-by-step explanation:
They have the same slope(5), meaning that they are parallel. since they are parallel they will never touch, thus there are no solutions
What’s the solution for x- 6 = 4

Answer:
For the first: [tex]x=-23[/tex] and [tex]x=17[/tex]
For the second: [tex]x=5[/tex]
Step-by-step explanation:
Answer:
x=17 for the first and x=5 for the second.
Step-by-step explanation:
First picture
Opposite angles of two intersecting lines are equal.
So the angle opposite the 100 degree angle on line c is also 100.
Since a, b, and c are all parallel, the angles made by the intersecting line r, are also all equal (these are corresponding angles).
So 5x + 15 = 100
5x = 85
x = 17
Second picture
Adjacent angles add up to 180 degrees. So the angle opposite 52 is 180-52=128.
[tex]2^{2x-3}=128\\\\2x-3 = 7\\2x = 10\\x=5[/tex]
