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 = 9
Add 3 to each side of the equation:
8t = 12
Divide each side by 8:
t = 1.5
8t = 36 t = 36/8 = 18/4 9/2 = 4.5
-8t = -152 t = 19

Since 1 ton is equal to 2,000 lb, 8T is equal to 16,000 lb.
15t = 17 + 8t -24 15t - 8t = 17 - 24 7t = -7 t = -1
8t equals -42 = -34
8t = 36 t = 36/8 = 18/4 9/2 = 4.5
-8t = -152 t = 19

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.
Since 1 ton is equal to 2,000 lb, 8T is equal to 16,000 lb.
15t = 17 + 8t -24 15t - 8t = 17 - 24 7t = -7 t = -1
If you mean 8t+3-t then it is 7t+3 simplified

t=-2
So you start by adding 8t+5t which equals 13t. So 13t=220. Now you divide by 13 so t=220/13 Hope I helped!
