A company mixes pecans, cashews, peanuts, and walnuts to make a batch of mixed nuts.
Pachacha [2.7K]

Answer:

500 lbs of mixed nuts

Step-by-step explanation:

15.4% of mixed nuts = 77 lbs of pecans

Divide the weight of pecans by the percent of mixed nuts to find how many pounds of pecans equal 1% of the mixed nuts:

77 / 15.4 = 5,  so 5 lbs equals 1% of mixed nuts

Now multiply that number by 100 to get 100% of mixed nuts:

5 x 100 = 500

Therefore, there are 500 lbs of mixed nuts in a batch altogether.

To check, 15.4% = 15.4/100 = 0.514

Therefore, 15.4% of 500 = 0.514 x 500 = 77

Thereby proving that 15.4% of 500 is 77.

                    8*d-5-(6*d+8)<0  

Step by step solution :

Step  1  :

1.1    Divide both sides by  2  

     d-(13/2)  < 0

Solve Basic Inequality :

1.2      Add  13/2  to both sides

            d < 13/2

Inequality Plot :
