Answer:
Step-by-step explanation:
6t = -21
3t-7 = 5t simplifies by subtracting 5t on both sides, then adding 7 on both sides:
3t -5t -7 +7 = 5t-5t+7
-2t = 7
t = -7/2
Then 6t = 6*-7/2 = -21
For the decimal rounded to the nearest tenth, 5 is is greater than numbers 1-4. So 5 rounds the 1.
0.2
0.2 in fraction form is 1/5.
