20 less than (-20) a number (n) is more than (>) twice the same number (2n)
-20+n>2n
minus n both sides
-20>n
n<-20
Answer:
It’s a obtuse triangle/scalene triangle
Step-by-step explanation:
Giving the information that is provided if the sides are not equal then it seems to be that the correct answer would be Obtuse Scalene

Answer:
mean-11
mode-none
range-10
median-12
Step-by-step explanation:
Let n = the hours elapsed when the two trains are 660 miles apart.
Let the first train travel east and the second train travel west.
The distance traveled by the first train is
x = (50 mi/h)*(n h) = 50n mi
The distance traveled by the second train is
y = (60 mi/h)*(n h) = 60n h
The distance between the two trains after n hours is
x + y = 50 n + 60n = 110n mi
Because this distance is 660 miles, therefore
110n = 660
n = 6 hours
Answer: 6 hours
