To evaluate the expression with the given value of y, substitute that given value for every y in the expression. So, since y = 6.8, substitute each y for 6.8 and solve like so:
Thus, the answer is 3.5.

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 !
