Question

-4 is less than or equal to 2t + 5 which is less than 11

Answer 1

Not sure what you’re trying to find but here’s the simplified version:

-4<=2t+5<11
-9<=2t<6
-9/2<=t<3

Answer 2

Answer:

Step-by-step explanation:

-4≤2t+5<11

subtract 5 from each inequality

-4-5≤2t+5-5<11-5

-9≤2t<6

divide by 2

-9/2≤2t/2<6/2

-4.5≤t<3

or t∈ [-4.5,3)
