Answer:
Step-by-step explanation:
Let the number TJ thinks of be n.
If he finds 1/3 of the number, the expression that models this situation is expressed as:
1/3 of n
= 1/3 * n
= n/3
hence the expression that models the scenario is n/3
1/3n-5
A = L x W
A = 108
108 = L x W
L = 2w - 6
108 = (2w-6) (W)
-9/10
check answer:
number + additive inverse = 0
9/10 + -9/10 = 0
