Final answer:
To find the value of k in the equation 5k - 2k = 121, simplify the equation and then solve for k. The value of k is 40.33 (rounded to two decimal places).
Step-by-step explanation:
To find the value of k in the equation 5k - 2k = 121, we need to simplify the equation and then solve for k.
Combining like terms, we get 3k = 121.
To solve for k, we divide both sides of the equation by 3: k = 121/3.
So, the value of k is 40.33 (rounded to two decimal places).
