What is -15.5t + 13.24 = -13.44 + 10.56 – 3.1t
Tatiana [17]
First, subtract 13.24 from both sides of the equation and add -3.1t on both sides of the equation. This isolates the variable t:

-15.5t + 3.1t = -13.44 + 10.56 - 13.24

Now combine the numbers on both sides of the equation and solve for t:

-12.4t = -16. 12
       t =  1.3

Hope this helps!

can someone explain this to me? thank you! (and I do apologize for it not being the correct way before, I didn't do that on purp
Kisachek [45]
D = 1/2 a t^2 is given. And it wants you to find t in terms if a and d. Which means, you need to arrange the equation and let t be alone.

If you let t^2 alone ;

2d/a = t^2

And square root t^2 will give you t ;
SquareRoot(2d/a) = t

The answer is (2)
