7-3(8t-10)=85
+3 +3
7(8t-10)=88
>distribute<
7x8t = 56t
7x-10 = -70

56t + 70 = 88
-70 -70
56t=18
56t/56 18/56
t= .3

i know this probably isnt correct
im in algebra 1 in case that helps at all?

2. If tan (x +y ) = x then dy/dx is???

3. suppose f(3)=2
f' (3) =5
f'' (3) = -2

then d^2 / dx^2 of (f^2 (x)) at x=3 is equal to

* then answer to that problem is 42 which made me think that how i solved it was wrong..

i completely forgot the rules when you multiply, subtract, divide and add things with exponents!

okay, when you multiply, say

1.29 x 10^3 x 3 x 10^17

would it be 3.87 x 10^20, or 1.47 x 10^21? i add the exponents right?

and another one:

3 x 10^17
------------- (divided by)
5.4 x 10^5

you subtract right? so...5.5 x 10^11??

thanks a lot!
