Answer:

8(k+2)-4k>8+2k-6

Step-by-step explanation:

To figure out how they compare, we can substitute 7 into the equation:

8+(7)2-6\\8+14-6\\22-6\\16\\

8((7)+2)-4(7)\\8(9)-28\\72-28\\44

As you can see from the answers we got, 8(k+2)-4k>8+2k-6, when k=7.

72:150 (72/150)

72/150 

= 0.48

0.48(100) = 48

... 48%
