To find the value of the expression -6(0.5x-1.5)-4.5x-8 when x=2/3, we first need to plug in the value of x into the expression:

-6(0.5(2/3)-1.5)-4.5(2/3)-8

Next, we simplify the expression:

-6(1/3-1.5)-3-8
-6(-1.17)-11
7.02-11
-3.98

Therefore, the value of the expression -6(0.5x-1.5)-4.5x-8 when x=2/3 is -3.98.
