Answer:

x = 3.5

Step-by-step explanation:

\frac{3}{5} (10x + 15) = 30

10x + 15  = 30 * \frac{5}{3}  

10x + 15   = 10 * 5

10x + 15   = 50           {Subtract 15 form both sides}

         10x = 50 -15

        10x = 35         {Divide both sides bt 10}

    10x/10 = 35/10  

          x = 3.5

Can someone please answer all parts?? Extra points for this one!
Brilliant_brown [7]
     <span>a) 
Acceleration of stone = 10 

Integrate: 
So velocity = 10t 

Integrate again: 
So distance from starting point = 5t^2 

Distance from ground = 450-5t^2 

b) 
450 - 5t^2 = 0 


9.48 seconds 

c) velocity = 10t 

Put the time into this to give: 

94.8 m/s 

d. 

Velocity = 10t + 5 

Integrate again: 

5t^2 + 5t 


Solve 
5t^2 + 5t = 450 

Gives 9 seconds</span>
