Casey did a science experiment to find out which brand of popcorn popped the most kernels. The first brand had 123 kernels pop. The second brand had 108 kernels pop. To the nearest ten, about how many kernels popped in all?

230

Step-by-step explanation:

The answer is 230 because if you add 123 and 108 together you get 231 but since we are rounding to the nearest 10 it would be 230 because 231 is closer to 230 than it is to 240.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
