Answer:
The amount of propellant is 52.770 ml of spray paint
Step-by-step explanation:
We are given
0.01895 ml of propellant in one milliliter of spray paint
so,
0.01895 ml of propellant = 1 milliliter of spray paint
We can divide both sides by 0.01895
ml of propellant = 
ml of spray paint
1 ml of propellant = ml of spray paint
now, we can divide right side
and we get
1 ml of propellant = 52.770 ml of spray paint
The amount of propellant is 52.770 ml of spray paint
Just look up a linear calculator.
Answer:
y=20 , x =30
Step-by-step explanation:
x+y=50;
20x+30y=1200
20x+20y=1000, multiplying the top by 20
-20x-30y=-1200, subtracting the second.
-10y=-200
y=20 adult tickets ($600)
x=30 student tickets ($600)
(add up to $1200)
A <u>counterexample</u> is something that proves a statement, or equation, wrong. A counterexample is used in math when someone creates a theorem, writes an equation, or creates a new rule and someone proves it to be false.
<u>For Example:</u>
Let's say that I said <em>an even number plus an odd number always equals an even number</em>. A counterexample of that would be 4 + 5 = 9, because 9 is odd, therefore proving the statement wrong.
The answer is 7/3 or 2 1/3
