Answer:

10 pens

Step-by-step explanation:

Find out how much pens she needs to sell to get $15, to get $15, exclude out how much Elena has.

$20 - $5 = $15

Now divide.

Can someone walk me through the steps: Steve increases his math average by 9 points over a period of 15 weeks. How many points p
ozzi

hmmm units rates are just a matter of one above the other.

in this case is points/week.

9/15  points/weeks, we can just divide 9 ÷ 15 = 0.6, or 3/5.

so 0.6 points/weeks.

Can someone explain how to solve this?
Irina18 [472]

Answer:

(-8,8)

Step-by-step explanation:

Simplify |n| + 4 < 12.  To do this, subtract 4 from both sides.  This results in:

|n| < 8.  The solution set includes all real numbers between -8 and 8, but not -8 itself or 8 itself.
