Answer:
The sweaters cost $35 each.

The skirt was $20, so you would subtract 20 from 160. that equals 140. Then you would divide 140 by 4. that would equal 35. So the answer is $35.
 
        
             
        
        
        
<em>The answer is 10:7, 10/7, 10 to 7. Whichever it's asking for. As long as you know the ratio is 10 rock songs to 7 country songs.
</em><em /><u>
</u><em />This problem can be a simple fraction simplification problem. Here's what I mean:
<em>
</em><em />So, we have 40 rock songs and 28 country songs. Let's put that into a fraction:
<em>
</em>
<em>
</em>To simplify this as much as possible, all we have to do is find the greatest common multiple and divide it by both numbers. the GCF is 4, so all you have to do is divide 40 by 4 and 28 by 4 to get your ratios.

Answer:
x=12
Step-by-step explanation:
-5= x/2.4
multiply both sides by 2.4 to isolate x
-5*2.4= (x/2.4)*2.4
12=x
