A nut mixture of peanuts and pecans at a small fair is $1.00 per pound of peanuts and $4.25 per pound of pecans. Over the entire
34kurt
Hello!

You can solve this algebraically

p + n = 115

p + 4.25n = 358.75

Subtract the two equations to eliminate p

-3.25n = -243.75

Divide both sides by -3.25

n = 75

Put n into the first equation

p + 75 = 115

Subtract 75 from both sides

p = 40

The answers are,

40 pounds of peanuts were sold
75 pounds of pecans were sold

Hope this helps!

Which of the following equations describes the line shown below , check all that apply
Bond [772]
The line is passing through the y-axis at 3. The slope of the line is 3.
So your equation would be y = 3x + 3.

Now solve A through F to see which equation(s) matches the line.

A. y + 6 = 3(x + 3)
     y + 6 = 3x + 9
     y = 3x + 3

B. y + 6 = 3(x + 1)
     y + 6 = 3x + 3
     y = 3x - 3

C. y - 6 = 3(x - 3)
     y - 6 = 3x - 9 
     y = 3x - 3

D. y - 6 = 3(x - 1)
     y - 6 = 3x - 3
     y = 3x + 3

E. y = 3x + 2

F. y = 3x + 3

Which letters equaled y = 3x +3?
A, D, and F.

The equations that describe the line are A, D, and F.
