Answer:
![\[t\leq -13\]](https://tex.z-dn.net/?f=%5C%5Bt%5Cleq%20-13%5C%5D)
Step-by-step explanation:
Given inequality is ![\[−3t\geq39\]](https://tex.z-dn.net/?f=%5C%5B%E2%88%923t%5Cgeq39%5C%5D)
Simplifying:
![\[-t\geq \frac{39}{3}\]](https://tex.z-dn.net/?f=%5C%5B-t%5Cgeq%20%5Cfrac%7B39%7D%7B3%7D%5C%5D)
![\[=>-t\geq13\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E-t%5Cgeq13%5C%5D)
Sign of the inequality changes of making both sides negative.
![\[=>t\leq -13\]](https://tex.z-dn.net/?f=%5C%5B%3D%3Et%5Cleq%20-13%5C%5D)
Hence the solution for the given inequality is represented by
This means that the original inequality will be true only for those values of t which are less than or equal to -13.

Answer:
12 dimes
Step-by-step explanation:
Let q represent the number of quarters. Then the number of dimes is 16-q and the total value is ...
0.25q +0.10(16 -q) = 2.20
0.15q +1.60 = 2.20 . . . . . . . simplify
0.15q = 0.60 . . . . . . . . subtract 1.60
q = 4 . . . . . . . . . . . divide by 0.15
16-q = 12
There are 12 dimes in the collection.
