Mary’s desk was 67.94 inches long, Joe’s desk was 78.26 inches long and Troy’s desk was x inches long. If the length of all the desks combined was 214.62 inches, how long was Troy’s desk?

Answer:

68.42

Step-by-step explanation:

We know that when we add the lengths of all of the desks together, the total is 214.62. Based on that information, we can set up the following equation: 67.94 + 78.26 + x = 214.62. From there, all you have to do is add 67.94 + 78.26 to get 146.2. Lastly, you simply do 214.62 – 146.2 to get 68.42. Hope this helps!
