d=55t solve for t: help me to understand how to do this
d=55t
The equation states that d is equal to 55 times some number. So d divided by 55 equals t.
d/55 = t
To solve the equation d = 55t for t, we need to isolate the variable t on one side of the equation. Here's an explanation of the steps involved:
1. Start with the equation: d = 55t.
2. To isolate t, we want to get rid of the coefficient of 55 that is multiplied with t. We can do this by performing an operation that "undoes" the multiplication.
3. Since 55 is being multiplied with t, we can divide both sides of the equation by 55. This will cancel out the multiplication on the right side, leaving us with just t.
d/55 = (55t)/55.
4. Simplifying the right side gives: d/55 = t.
We now have t isolated on one side of the equation.
Therefore, the solution for t is t = d/55.
