Let's solve this by substitution. Note that y is defined: y = 2x - 2. Subst. 2x - 2 for y in the other equation: -6x + 3(2x - 2) = 18.
Then -6x + 6x - 6 = 18. Unfortunately, -6 does not equal 18, so there is no solution. The graphs of these two lines are parallel.
30 = 5/6 of x
30 = 5/6 (x)
30 ÷ 5/6 = x
30 × 6/5 = x
180/5 = x
36 = x

The <em><u>correct answer</u></em> is:
He can buy 3 packs of 10 or 30 single pieces.
Explanation:
He needs 30 pieces. Since they are sold in 10 packs, it would take 30/10 = 3 packs of 10.
Other than this, the pieces are sold as singles. This means he could also buy 30 single pieces.
Hello!
First you have to find out how many hours she works
She worked 8 hours a day for 5 days
8 * 5 = 40
Divide this by the money she earned
720 / 40 = 18
The answer is $18 an hour
Hope this helps!
