5. A race course is 99 meters long. There are trees

along 38 meters of the course. How long is the part

of the course without trees?

unit

61

Step-by-step explanation:

99 minus 38

61 meters

Step-by-step explanation:

To find this answer, you need to subtract the length with trees from the total length of the course. With this information, you get an equation that looks something like x + 38 = 99, with x being the length of the course without trees.

Subtract 38 from both sides:

x + 38 = 99

- 38 - 38

x = 99 - 38

Simplify:

x = 61
