If the required time is measured from 0 then s = t2 - 8t, therefore 9 = t2 - 8t, which can be written as t2 - 8t - 9 = 0 This equation can be factored as (t - 9)(t + 1) = 0 As we are only concerned with a positive time then the answer is when t - 9 = 0, thus t = 9 seconds.

8t equals -42 = -34
-8t = -152 t = 19
It is an expression that can be simplified to -8t-38

Radius = 8T/(2*pi) = 4T/pi
15t = 17 + 8t -24 15t - 8t = 17 - 24 7t = -7 t = -1
If you mean 8t+3-t then it is 7t+3 simplified
The "answer" is the number that can be put in place of 't' and makes [ 8t-3=9 ]a true statement.Here's how to find out what it is:8t - 3 = 9Add 3 to each side of the equation:8t = 12Divide each side by 8:t = 1.5
Since 1 ton is equal to 2,000 lb, 8T is equal to 16,000 lb.
8t = 36 t = 36/8 = 18/4 9/2 = 4.5
The expression 15-t plus 8t-13 simplifies to 7t + 2.
7s plus 8t plus 10s plus 12t can be simplified to 17s plus 20t.
