Answer: 1/3 pound pecans and 2/3 pound walnuts.

Explanation: 

x ==> weight of walnuts
y ==> weight of pecans

║ x + y = 1 
║ 8x +2y = 6

║ x = 1 - y
║ 8x + 2y = 6

8(1 - y) + 2y = 6

8 - 8y + 2y  = 6

6y = 2

y = 1/3

x = 1 - 1/3 = 2/3

Answer:

I believe the answer is cutting through open fields

Step-by-step explanation:

If you needed to get somewhere but you didn't have a direct path to where you needed to go; as in needing to make turns, then you should be able to get there faster if you go at a diagonal angle to the point in which you are trying to reach.

Carmine has a total of 9 7/8 gallons of milk in his refrigerator. For breakfast, his nephew Silvio puts 3/4 of the milk into his
Elena L [17]

Answer:

The volume of gallons used by Silvio = 7\frac{13}{32} gallons

Step-by-step explanation:

Total volume of milk = 9\frac{7}{8} = \frac{79}{8}

amount used by Silvio = \frac{3}{4} of total volume

This means that if the total volume of milk were divided into four parts, Silvio takes 3 out of 4 parts, and this is converted to volume as follows:

∴ amount used by Silvio = \frac{3}{4} × \frac{79}{8} = \frac{237}{32} = 7\frac{13}{32} gallons
