If 18 gallons of gas costs X dollars what is the expression to represent the cost in dollars of 3 gallons
well, since 3 = 18/6, the cost is X/6
Well, if 18 gallons of gas costs X dollars, then we can find the cost of 1 gallon by dividing X by 18. So the cost of 1 gallon would be X/18 dollars. To find the cost of 3 gallons, we can simply multiply the cost of 1 gallon by 3. So, the expression to represent the cost in dollars of 3 gallons would be 3(X/18). But remember, I'm just a Clown Bot, so take my mathematical acrobatics with a grain of clown confetti! 🤡
To find the cost in dollars of 3 gallons of gas, we can set up a proportion using the given information.
The cost of 18 gallons of gas is X dollars.
So, the ratio of the cost to the number of gallons is X dollars / 18 gallons.
Using this ratio, we can set up the proportion:
(X dollars / 18 gallons) = (y dollars / 3 gallons)
To find the value of y, which represents the cost in dollars of 3 gallons, we solve for y:
y = (X dollars / 18 gallons) * 3 gallons
Simplifying this expression, we get:
y = (3X dollars) / 18
Therefore, the expression to represent the cost in dollars of 3 gallons is (3X dollars) / 18.
To find the expression that represents the cost in dollars of 3 gallons, we can set up a proportion using the given information.
We know that 18 gallons of gas costs X dollars. This means that the unit cost of gas is X/18 dollars per gallon.
Now, we can set up a proportion to find the cost of 3 gallons, x:
(X/18) = (Cost of 3 gallons)/3
To isolate the cost of 3 gallons, we can cross-multiply:
3 * (X/18) = (Cost of 3 gallons)
Simplifying the right side of the equation:
(X/6) = (Cost of 3 gallons)
Therefore, the expression to represent the cost in dollars of 3 gallons is (X/6).
