Factor 1/8 out of 1/8x-49/8​
svetoff [14.1K]

Answer:

1/8(x - 49)

Step-by-step explanation:

When we factor out something, we are basically finding common factors from multiple terms to take out. Example:

ab + ac; factored out: a(b + c)

If we want to factor out 1/8 from 1/8x - 49/8, we simply divide the two terms by 1/8.

\frac{1/8}{1/8x} The 1/8 cancel out giving us x so:

1/8(x - __)

The next term,

\frac{49/8}{1/8}

When two fractions divide, you flip the bottom one and multiply them both,

\frac{49}{8} *\frac{8}{1}

giving us 49.

The answer is: 1/8(x - 49)

The number of bags of mulch you need to cover a planting area varies jointly with the area to be mulched (a) in sq ft and the de
Lena [83]

Answer:

  22 2/9

Step-by-step explanation:

When z "varies jointly" with x and y, it can be described by the formula

   z = kxy

Here, we have bags of mulch (n) varying jointly with area (a) and depth (d), both in feet. The given information can let us find the value of k.

  n = kad

  10 = k·(120)(1/4)

  10/30 = k = 1/3 . . . . . divide by the coefficient of k

Now, we can fill in the other values of interest.

  n = (1/3)·(200)·(1/3) = 200/9

  n = 22 2/9

You need 22 2/9 bags of mulch to cover 200 ft² to a depth of 4 inches.

_____

<em>Comment on the problem</em>

This problem requires the formula be written with both area and depth expressed in feet, yet it gives depth in inches. The formula can also be written using depth in inches. In that case, k = 1/36.
