71. the expression 14x 3 represents the perimeter of the triangle. what is the length of the third side? 3x 2 7x - 4
Alex

The Length of third side of the triangle is 4x +5

What is the Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.

How to determine the length of the third side of the Triangle?

The given parameters are:

Length of the first side = 3x+2

Length of the second side =7x-4

Perimeter of the triangle =14x+3

Now, The perimeter is the sum of the sides of lengths

So, we have

Perimeter = sum of the sides of lengths

According to the question:

14x+3 =3x+2 +7x -4 + third side

Evaluate the like terms

14x-10x = -2 -3

third side = 4x + 5

Hence, The length of the third side of the triangle is 4x+5

A chemical company makes two brands of antifreeze. The first brand is 30% pure antifreeze, and the second brand is 75% pure anti
gtnhenbr [62]

Answer:

Let x = amount of 45% antifreeze

Let y = amount of 70% antifreeze

 

    EQUATION 1:   x + y = 150    (total of 150 gallons mixed)

 

    EQUATION 2:  .45x + .75y = .55(x + y)

 

Simplify and solve the system of equations

 

    Multiply second equation by 100 on both sides to remove the decimals

 

          45x + 75y = 55(x + y)

 

    Combine like terms

 

          45x + 75y = 55x + 55y

 

          45x - 55x + 75y - 55y = 0

   

          -10x + 20y = 0

 

      Now we have the following system of equations:

 

             x  +    y = 150

        -10x + 20y =     0

 

    Multiply the first equation by -10 to get opposite coefficients for x;  add the equations to eliminate x

 

          10x + 10y = 1500

         -10x + 20y =       0

        ------------------------------

                    30y = 1500

 

     Solve for y

 

           30y = 1500

 

               y = 50

 

     Since the total mixed gallons is 150, x = 150 - 50 = 100

 

So we need 100 gallons of the 45% antifreeze and 50 gallons of the 70% antifreeze
