Answer:

Step-by-step explanation:

\frac{28}{z}-\frac{z}{4}+1\frac{1}{8}=\frac{28}{4}-\frac{4}{4}+\frac{9}{8}\\\\=7-1+\frac{9}{8}\\\\=6+\frac{9}{8}\\\\=\frac{6*8}{1*8}+\frac{9}{8}\\\\=\frac{48}{8}+\frac{9}{8}\\\\=\frac{57}{8}\\\\=7\frac{1}{8}

Kai used fabric measuring 5 yards in length to make each costume for a school play. The relationship between the number of costu
Yuki888 [10]

The best interpretation of 2 in the given context is that; 2 represents the total length of fabric in yards purchased when no costumes were made.

<h3>Slope Intercept Form</h3>

We are given the relationship between the number of costumes that Kai made, x, and the total length of fabric that he purchased y, in yards as; y - 5x = 2

Where;

  • x is number of costumes made
  • y is total length of fabrics purchased.

Now, the general slope intercept form of an equation is given by; y = mx + c

Where c is the y-intercept which is the point where x is zero.

Thus, our equation can be rewritten as;

y = 5x + 2

Comparing with y = mx + c, we can say that c = 2

This means that at x = 0, y = 2.

In conclusion, the value 2 represents the length of yards purchased when no costumes were made.
