Let say
e=number of english teachers
m=number of math teachers
3 more english tahn math
e=m+3
ratio if e to m is 6:5
e:m=6:5
e/m=6/5
e=m+3
(m+3)/m=6/5
times 5m both sides
5(m+3)=6m
5m+15=6m
minus 5m both sides
15=m
e=m+3
e=15+3
e=18

Answer:
d. √74 units
Step-by-step explanation:
The distance formula is useful for finding the length of a line segment.
d = √((x2 -x1)^2 +(y2 -y1)^2)
Filling in the point coordinates L(-5, -3) and M(0, 4), we find the length of LM to be ...
LM = √((0-(-5))^2 +(4 -(-3))^2) = √(25 +49)
LM = √74 . . . units
Amir is incorrect. This is because 0.09 is 1/10 of 0.9 You can see this on a place value chart. Thousands, Hundreds, ones, tenths, and hundredths. Place down the values to see which one is greater. It is the 9 in the tenths place. 135.9. The tenths place is closer to the wholes than the hundredths place.

Answer:
(y-12)/4
Step-by-step explanation:
If g(x) is the inverse of f(x)
and f(x) = 4x + 12
f⁻¹(x) = g(x)
let f(x) be represented as y
f(x)
= y
y = 4x + 12
subtract 12 from both sides
y-12= 4x
divide both sides by 4
(y-12)/4 = x
so f ⁻¹ (y)= (y-12)/4 so g(x) = (x-12)/4
