t/6 + t/8 = 1

multiply by common denominator... 24

24 (t/6 + t/8 = 1)

4t + 3t =24

7t = 24

t = 24/7 = 3.4hrs

Answer/Step-by-step explanation:

<u>Given:</u>

Bracelets - $3

Necklaces - $6

<u>To Find:</u>

Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry. Write the ordered pair for the corresponding terms in the third column. Then graph the ordered pairs.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<u>Solve: </u>Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry.

<u>Bracelets:  </u>                                                      <u> Necklaces:</u>

0 = $0                                                               0 = $0

1= $3                                                                  1 = $6

2=$6                                                                  2 = $12

3=$9                                                                   3 = $18

4=$12                                                                  4 = $24

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<u><em>Solve: </em></u>Write the ordered pair for the corresponding terms in the third column.

Ordered Pair -

Two numbers written in a certain order.

Usually written in parentheses like this:

(12,13)

Where they cross over is the "0" point,

we measure everything from there.

The X Axis runs horizontally through zero

The Y Axis runs vertically through zero

(x, y )

Since it asking for Write the ordered pair for the corresponding terms in the third column.

Thus,

- Number of jewelry to cost -

we have:

Bracelets ⇒ ( 3, 9)

Necklaces ⇒ (3, 18)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then graph the ordered pairs.
