Yes! Let me help you!
Here is the original equation, lets solve this step-by-step
(x + 2)/4 = 5
Now, lets find out how. 
We must apply the inverse operation. 
4/2 is the reciprocal, so lets multiply that to both sides. 
4/2 = 2
5*4 = 20
4x + 8 = 20
      -8      -8            Subtract 8 from both sides. (Inverse operation) 
4x = 12
4x/4  = 12/4             Divide 4 by both sides (Inverse)
x = 12/4
x = 3           Simplified
Answer:  x = 3
        
                    
             
        
        
        
Answer:
<em>There are approximately 114 rabbits in the year 10</em>
Step-by-step explanation:
<u>Exponential Growth
</u>
The natural growth of some magnitudes can be modeled by the equation:

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
We are given two measurements of the population of rabbits on an island.
In year 1, there are 50 rabbits. This is the point (1,50)
In year 5, there are 72 rabbits. This is the point (5,72)
Substituting in the general model, we have:

![50=P_o(1+r)\qquad\qquad[1]](https://tex.z-dn.net/?f=50%3DP_o%281%2Br%29%5Cqquad%5Cqquad%5B1%5D)
![72=P_o(1+r)^5\qquad\qquad[2]](https://tex.z-dn.net/?f=72%3DP_o%281%2Br%29%5E5%5Cqquad%5Cqquad%5B2%5D)
Dividing [2] by [1]:

Solving for r:
![\displaystyle r=\sqrt[4]{\frac{72}{50}}-1](https://tex.z-dn.net/?f=%5Cdisplaystyle%20r%3D%5Csqrt%5B4%5D%7B%5Cfrac%7B72%7D%7B50%7D%7D-1)
Calculating:
r=0.095445
From [1], solve for Po:



The model can be written now as:

In year t=10, the population of rabbits is:

P = 113.6

There are approximately 114 rabbits in the year 10
 
        
             
        
        
        
Answer:
$74.41
Step-by-step explanation:
x = Amount of money Sylvia had in her account
Amount of money spent at the Grocery Store= $25.89
Remaining Amount of money after Grocery = $48.52
Hence, By adding the two amount above we get the amount Sylvia had in her account before grocery;
x = $25.89 + $48.52
x = $74.41
