How do you solve 10≤2x≤x+9? The answer says it's 5≤x≤9 but i have no idea how it got there

Answer:
Step-by-step explanation:
so why this kind of problem is so confusing is b/c it's 2 problems in one
if you were to expand this it look like this
10 ≤2x
and
2x ≤x+9
This is really saying.. that x has a range.. and that the 1st equations is the lower stop point, and that the 2nd equations is the upper stop point
once it's taken apart.. I bet you can solve it pretty quickly.
5≤x
and
x ≤9
then just put it back together in that confusing .. yet handy way to write it,
5≤x≤9

Answer:
Step-by-step explanation:
5x + 38 = 8x - 19
by transposing method,
5x - 8x = -19-38
-3x = -57
3x = 57
x = 57/3
x = 19

Step-by-step explanation:
Jason has 4 lengths of ropes
first is 
second is 
Third is ![0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}]](https://tex.z-dn.net/?f=0.3%5C%20m%5Capprox%2030%5C%20cm%5Cquad%20%5B%5Ctext%7B1%20m%20%3D%20100%20cm%7D%5D)
fourth is ![0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}]](https://tex.z-dn.net/?f=0.5%5C%20ft%5Capprox%206%5C%20in.%5Capprox%2015%5C%20cm%5Cquad%20%5B%5Ctext%7B1%20ft%3D12%20in.%7D%5D)
the total length of rope is the sum of four lengths
Answer:
Normal distribution or normal curve. It is most appropriate to report the mean for such a distribution
Step-by-step explanation:
