You can  put this solution on YOUR website! 5*( square root of X) + 1 = 3 
5sqrt(x) + 1 = 3 
5sqrt(x) = 2 
sqrt(x) = 2/5 
x = 4/25 
--------------------------------------- 
 
 
c) 2/3=2-(5x-3)/(x-1) 
 
 
(5x-3)/(x-1) = 4/3 
3(5x-3) = 4(x-1) 
15x-9 = 4x-1 
11x = 8 
x = 8/11 
-----------------------------
 
2) Solve algebraically and check your potential solutions:  
(square root of t+12)- t =0  
sqrt(t+12) = t 
t+12 = t^2 
t^2-t-12 = 0 
(t-4)(t+3) = 0 
t = 4 or to = -3 
----------- 
Checking: 
If t=4, sqrt(16) = 4 which is true 
-------- 
If to -3, sqrt(9) = -3 which is false 
--------- 
Final answer: t = 4 
==============================
 
3) The volume of a cube is given by V = s3, where s is the length of a side. Find the length of a side of a cube if the volume is 700 in3. Round the answer to three decimal places. 
I have s^3= 700 is this right( can you show me how to solve that) 
Answer: 
V = s^3 
700 = s^3 
s = cube root of 700 
s = 8.879..
