Answer:
x+7 oops x+15 ignore the first answer
Step-by-step explanation:
x+11-8/-2
first do -8/-2=4
so it is x+11+4
11+4
x+15 is the answer

Answer:
stationary time is 2 hours 30 minutes
Traveling time is 3 hours 30 minutes
Step-by-step explanation:
There are two distinct line types on the graph
the horizontal ones and the ones going towards the upper part
The horizontal ones represent the stationary positions while the climbing one represent the traveling time
The horizontal ones are;
3 to 3:30
4-5
6:30 to 7:30
Time here is ;
30
minutes + 1 hour + 1 hour = 2 hours 30 minutes
The traveling time;
2 - 3
3:30 to 4
5 to 6:30
7:30 to 8
1 + 30 min + 1hr 30 + 30
= 3 hours 30 minutes
white : milk : dark
w : m : d
The ratio of white to not white is 3:4
w : (m+d) = 3:4
The ratio of not dark to dark is 17:4.
(w+m) : d = 17:4
---------
We treat the colons as fraction bars and cross multiply.
4w = 3(m+d) = 3m + 3d
4w + 4m = 17 d
Subtracting,
4m = 17d - (3m+3d) = 14d - 3m
7m = 14 d
m/d = 14/7
m:d = 2:1
Since w:(m+d)=3:4 let's make m+d a multiple of 4.
m:d = 8:4
w : (m+d) = 3:4 = 9:12
w:m:d = 9:8:4
Answer: 9:8:4
Check:
white to non white 9 to 8+4=12 = 3:4, good
non dark to dark (9+8):4=17:4, good
