zaharov [31]

Answer:

The amount of peanuts to use is 5 pounds and that of cashews is 30 pounds.

Step-by-step explanation:

Let the amount of peanut to use to be x

Let the amount of cashews to use to be 35-x

Form equations to compare amounts for individual foods and the mixture

8x+15(35-x)=35(14)\\\\8x+525-15x=490\\\\7x=35\\\\x=5\\\\

So the pounds to be used for peanuts is 5 pounds

The pounds to be used for cashews will be 35-x= 35-5=30 pounds

Solve y-4=3x+5y for y
Inga [223]
<h3><u>The value of y is equal to (-4 - 3x)/4.</u></h3>

Because there are two variables and only one equation, we cannot solve for the exact value of y.

However, we can still get a value of y.

y - 4 = 3x + 5y

Subtract y from both sides.

-4 = 3x + 4y

Subtract 3x from both sides.

-4 - 3x = 4y

Divide all terms by 4.

(-4 - 3x)/4 = y
