Answer:

6

Step-by-step explanation:

    Pull out like factors :

  -12x + 72  =   -12 • (x - 6)  

Step  2  :

Equations which are never true :  

Solve :    -12   =  0  

A non-zero constant never equals zero.

Solving a Single Variable Equation :  

Solve  :    x-6 = 0  

Add  6  to both sides of the equation :  

                     x = 6

There are approximately 15 milliliters (mL) in 1 tablespoon (tbsp). Which expression can be used to find the approximate number
Greeley [361]
We develop the ratio between the number of milliliters present in 1 tablespoon and that is,
                               15 mL: 1 tablespoon
We let x be the number of millileter in 3 tbsp and it can be determined through the equation below.
                                x = 3 tbsp x (15 mL/ 1 tbsp) = 45 mL
Therefore, there are 45 mL in 3 tbsp.

Slope = (212 - 32)/(100 - 0)

Slope = 180 / 100

Slope = 18/10

Slope = 9/5
