Answer:
x = 24
Step-by-step explanation:
18 + 0.5x = 12 +0.75 x
18 - 12 = 0.75 x - 0.5x
6 = 0.25 x
24 = x
Answer:
21:50
Step-by-step explanation:
We need to find the ratio of 420 m to 1 km.
We know that,
1 km = 1000 m
So,
The ratio becomes,

So, the required ratio is 21:50.
tell the height, width and depth then we will help
F(x) = 6x + 5
g(x) = 6x - 5
f(g(x)) = 6(6x - 5) + 5 = 36x - 30 + 5 = 36x - 25
g(f(x)) = 6(6x+ 5) - 5 = 36x + 30 - 5 = 36x + 25
f and g are not inverse of each other.
