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

To find the time it takes for the object to move 9 feet, we set s = 9 and solve for t: 9 = t^2 - 8t Rearranging the equation gives t^2 - 8t - 9 = 0 Solving the quadratic equation, we find 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!
