Final answer:
To express t as a function of r and w from the equation 7r/t = 5w, simply rearrange it to t(r,w) = 7r / (5w).
Step-by-step explanation:
You have been asked to write the expression for t as a function of r and w based on the equation 7r/t = 5w. To isolate t, we need to perform the following steps:
- Multiply both sides of the equation by t to get rid of the fraction, which gives us 7r = 5wt.
- Next, divide both sides of the equation by 5w to solve for t, which yields t = 7r / (5w).
Therefore, t as a function of r and w is t(r,w) = 7r / (5w).
