Answer:
The five gallons is cheaper since 97.45 divided by 5 is equal to 19.49.
Step-by-step explanation:
Linear fonction's equation : y = ax
So only in y = 2x
2 is the constant of <span>proportionality</span>
They are the same because if you add a zero it doesnt change it
Let
x---------> the larger number
y---------> the smaller number
we know that
x+y=148------> equation 1
x=3y-2------> equation 2
substitute 2 in 1
[3y-2]+y=148--------> 4y=150---------> y=150/4------> y=37.5
x=3y-2----> x=3*37.5-2-----> x=110.5
the answer is
the larger number is 110.5
the smaller number is 37.5
