Answer 1

To find the value of k in the expression (5k-3)/(9+ k), we can equate it to a known value and solve for k. When Ok = 31, the value of k is 3.8.

Step-by-step explanation:

The given expression is (5k-3)/(9+ k).

To find the value of k, we can equate this expression to a known value and solve for k.

Let's consider Ok = 31. When we substitute this value into the expression, we get (5 * 31 - 3) / (9 + 31) = (155 - 3) / 40 = 152 / 40 = 3.8.

Therefore, the value of k when Ok = 31 is 3.8.
