Final answer:
To solve for X when Z = 4.0 and Y = 6.8, substitute the values into the formula Z = Y/X and rearrange to get X = Y/Z. Thus, X = 6.8 / 4.0, which equals 1.7.
Step-by-step explanation:
The equation given is Z = Y/X, and we need to solve for X. If Z = 4.0 and Y = 6.8, you can substitute these values into the equation to find X. This gives us the equation 4.0 = 6.8/X. To solve for X, you want to isolate it on one side of the equation. You can do this by multiplying both sides by X and then dividing both sides by 4.0.
So, the calculation would be:
X × 4.0 = 6.8
X = 6.8 / 4.0
X = 1.7
Therefore, the value of X is 1.7.
