Answer:
see below
Step-by-step explanation:
side opposite 90 angle = x 
sides opposite 45 angle = x
the multiplication and division by
should be self explanatory
1. x = 5, y = 5
2. v = 10, u = 10
3. x =
, y = 
4. m = 5, n = 
5. a =
, b = 
6. a =
, b = 
45 on each bus. 365 minus 5 in cars is 360. Divided by 8 to get 45.
75x + 90(15-x)=88(15)
75x+1350-90x = 1320
-15x + 1350 = 1320
-15x= -30
x=2
the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons
Hope this helps.
