Divide $31.75 by 2 to find out the cost for 1 pack. Then multiply that total times 3 to get the total for 3 packs.
31.75/2 = 15.875
15.875 x 3 = 47.625, rounded to $47.63
9514 1404 393
Answer:
x = 4
Step-by-step explanation:
I like to put these in the form f(x) = 0. We can do that by subtracting the right side. Common factors can be cancelled from numerator and denominator, provided they are not zero.

_____
If you leave the numerator as (x-3)(4-x), then there are two values of x that make it zero. Because x=3 makes the equation "undefined", it cannot be considered to be a solution.
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept → (0, b)
From the graph we have the points (4, 4) and (0, 3) → b = 3.
We have the equation:

The formula of a slope:

Put the coordinates of the points:

Finally we have:
