Set up 2 equations.(x = number of people in first class, y = tourist class)
30x + 25y = 1360
x + y = 52
You have 2 equations and 2 unknown. You can solve them.
I like to use the substitution method
Because y = 52 - x
Then 30x + 25(52 - x) = 1360, solve for x.
30x + 1300 - 25x = 1360
5x = 60
x = 12
Use the x to solve y
30(12) + 25y = 1360
360 + 25y = 1360
25y = 1000
y = 40

Answer:
length ofGH
Step-by-step explanation:
distance=√{(-2+9)²+(-6+4)²}=√{7²+(-2)²}=√53=7.28=7.3 units
will she would have rode 4 3/5 miles in all.
2 3/10+2 3/10=4 3/5
that is 2 3/10 there and 2 3/10 back so you would add that together.
MILES IN ALL 4 3/5
Hope this helps
