A small tree was planted at a height of 8 feet. The tree has been planted for 16 months, and is now 59.2 feet tall. Which equation could be used to find x, the average number of feet the tree grew each month?

8+16x=59.2 or 16x+8=59.2

Step-by-step explanation:

if it was 8 feet when it was planted and it grew x feet for 16 months ending at 59.2 ft then you would multiply 16 times x and add the original 8 ft which will equal 59.2 feet.

Answer

Step-by-step explanation:

So what you do is first convert - 5 1/4 to - 21/4 then you multiply -21/4 x - 3/2 and is 63/8 and there for the final answer is 7.785 and finally this closely rounds to 10.
