Determine if the ordered pair (6, 4) is a solution to the inequality y is less than three fourths times x minus 3.

The correct answer is A. No, because (6,4) is above the line.

Step-by-step explanation:

Just find a graphing calculator and enter the equation. When graphed, the slope goes under the point (6,4). So therefore, it is above the line and not a solution. Making the correct answer A.

There are 30 gallons of anti freeze of  first brand and 120 gallons of anti freeze of second brand.

Step-by-step explanation:

Since we have given that

Percentage of anti freeze in first brand = 35%

Percentage of anti freeze in second brand = 85%

Percentage of anti freeze in mixture = 75%

Total number of gallons of mixture = 150 gallons

We will use " Mixture and Allegation":

 First brand         Second brand

      35%                      85%

                      75%

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

85%-75%         :            75%-35%

    10                :               40

     1                 :                 4

So, Number of gallons of anti freeze in first brand is given by

Number of gallons of anti freeze in second brand is given by

Hence, there are 30 gallons of anti freeze of  first brand and 120 gallons of anti freeze of second brand.
