<span>While the output is any variable going out of the system.
In this case the output is the amount of water which leaked out.</span>
Answer:
2.60
Step-by-step explanation:
4.70 hotdogs
fries 1.25
water 2.60= 8.55-10=1.45
3s + 135 = 4.5s + 45
Now move the variables and coefficients
135 = 1.5s + 45
And then the numbers
90 = 1.5s
Simplify
90/1.5 = 1.5s/1.5
60 = s
Hope this helps!
