    4(x + 1) - ax = x + 5
4(x) + 4(1) - ax = x + 5
     4x + 4 - ax = x + 5
     - x              - x
     3x + 4 - ax = 5
           - 4         - 4
            3x - ax = 1
        x(3) - x(a) = 1
            x(3 - a) = 1
              3 - a   3 - a
                      x = 1/(3 - a)

4(x+1)-ax=x+5 

4x+4-ax=x+5

 
    Expand 

4x-ax=x+5-4

 
     Subtract \ 4 \ from \ both \ sides 

4x-ax=x+1 

4x=x+1+ax         Add \ ax \ to \ both \ sides 

4x-x=1+ax

 
         Subtract \ x \ from \ both \ sides 

3x=1+ax

 
 

3x-ax=1&#10;&#10; &#10;            <span>Subtract \ ax \ from \ both \ sides  
</span>
x(3-a)=1&#10;&#10; &#10;    

x= \dfrac{1}{3-a}

X over 85 = 72 over 100
gayaneshka [121]

Answer:

X=61.2

Step-by-step explanation:

x/85   =     72/100

x*100/8500           =    6120/8500

x*100 must equal 6120 therefore x must be 61.2 because 61.2 * 100 is 6120

The volume of a rectangular prism whose dimensions are binomials with integer coefficients is modeled by the function V(x) = x^3
Levart [38]

Answer:

The missing dimension of the prism is (x-4)

Step-by-step explanation:

Here, we want to find the missing dimensions of the prism

To get the volume, we are to multiply three dimensions since we are talking about volume

Mathematically, to find the third dimension, we need to divide the original polynomial by the product of the two other dimensions

The product of the two other dimensions is;

(x-1)(x-9) = x^2-9x-x + 9

= x^2-10x+ 9

So we divide;

(x^3-14x^2+49x-36)/(x^2-10x+ 9)

We can use long division to get this

using long division, the answer here is x-4

The cake density is 0.454 ounce per cubic inch and the fair price is $0.20 per ounce. What should be a fair price for each cake?
aleksklad [387]

Answer:

price = x * 0.2

or

price = x * 0.454 * 0.2

Step-by-step explanation:

In this case we must know either the mass of the cake or its volume.

Given the case that we know the mass of the cake, it would be:

price = x * 0.2

where x is the mass of the cake in ounces, that is to say if for example a cake has a mass of 10 ounces, it would be:

price = 10 * 0.2 = 2

which means that each cake costs $ 2

Given the case of the volume, we must first multiply the density by this volume in order to calculate the mass and finally the price.

price = x * 0.454 * 0.2

where x is the volume of the cake in cubic inches, if for example the volume is 10 cubic inches it would be:

price = 10 * 0.454 * 0.2 = 0.908

which means that each cake costs $ 0.9
