5t^2 - 25t - 10 = 0
Looks like a quadratic formula problem, and it might be ugly. The discriminant, by simple visual inspection, tells me this has two real roots.
Let us divide through by 5 to simplify things
t^2 - 5t - 2 = 0
different parabola, but crosses X axis at same place
t = -b +/- sqrt(b^2-4ac)/2a
a = 1
b = -5
c = -2
-(-5) +/- sqrt[(-5)^2 - 4(1)(-2)]/2(1)
5 +/- sqrt(17)/2
ugly, but true

What is t if 5 times t minus 5 over -10 equals 70?
Depends on which question you're asking: 1) (5t-5)/-10=70 5t-5=-700 5t=-695 t=-139 2) (5(t-5))/-10=70 5(t-5)=-700 5t-25=-700 5t=-675 t=-135
How do you solve the problem '4p add 5t minus p add 10t'?
"Add" means "+" and "minus" means " - "; so we have:4p + 5t - p + 10tNow group the numbers with variables together:4p - p and 5t + 10t, and then simplify:3p + 15t
What is the answer for 5t-1 equals - 11?
5t - 1 = -11 Therefore, 5t = -10 t = -10/5 t = -2
What is 5t plus 5 for t equals 1?
If t=1, then 5t = 5 and 5t + 5 = 10
Cos 5t cos 3t -square root 3 2 - sin 5t cos 3t?
The answer to the math question Cos 5t cos 3t -square root 3 2 - sin 5t cos 3t equals 0. In order to find this answer you will have to find out what each letter is.

Cos 5t cos 3t square root 3 2 sin 5t cos 3t?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses). "square root 3 2" seems unlikely. Also, there is a minus sign at the end, with nothing following!
