3:3 3 apples 3 pineapples
Answer:
[24 -12 6]
7 3 0
Unless you also multiply the bottom, then it's:
[24 -12 6]
42 18 0
Step-by-step explanation:
6 * 4 = 24
6 * -2 = -12
6 * 1 = 6
----------------
6 * 7 = 42
6 * 3 = 18
6 * 0 = 0
Y=6 because they are inverse of each other so opposite or flipped
Answer:
7 / 23 or 30.434782608696%
Step-by-step explanation:
If you mean the 7 to 23 ratio, then this is the answer
Create a system of 2 equations
Let x be daily fee and y the mileage charge, then
4x + 370y = 244.50...........(1)
3x + 190y = 161.50..............(2)
If we multiply (1) by 3 and (2) by -4 and add the 2 equations we eliminate x:-
12x + 1110y = 733.50
-12x - 760y = -646 Adding :-
350y = 87.5 so y = 0.25
Plugging y = 0.25 into eqation (1) we get 4x = 244.50 - 0.25 * 370
giving x = 38
Answer is daily fee = $38 and mileage charge = $0.25 per mile.
