Answer:  0.6 grams per cm

===================================================

Explanation:

Pick any column and divide the weight over the length

column 1:  9/15 = 0.6

column 2:  12/20 = 0.6

column 3:  18/30 = 0.6

column 4: 30/50 = 0.6

The weight per cm is 0.6 grams per cm

---------

Another way you could look at is like so

9 g = 15 cm

9/15 g = 15/15 cm

0.6 g = 1 cm

We divided both sides by 15 to turn "15 cm" into "1 cm". Think of "per cm" as "per 1 cm". This works for any other column as well.

[See Below]

Step-by-step explanation:

___________________________________________________

✦ To figure out the rule of this table you must Add, Subtract, Multiply, and Divide each line to find similarities.

___________________________________________________

✧ Line 1:

  • [tex]15+9=24[/tex]
  • [tex]15-9=6[/tex]
  • [tex]15*9=135[/tex]
  • [tex]15[/tex] ÷ [tex]9=1.66r[/tex]

___________________________________________________

✧ Line 2:

  • [tex]20+12=32[/tex]
  • [tex]20-12=8[/tex]
  • [tex]20*12=240[/tex]
  • [tex]20[/tex] ÷ [tex]12=1.66r[/tex]

___________________________________________________

✧ Line 3:

  • [tex]30+18=48[/tex]
  • [tex]30-18=12[/tex]
  • [tex]30*18=540[/tex]
  • [tex]30[/tex] ÷ [tex]18=1.66r[/tex]

___________________________________________________

✧ Line 4:

  • [tex]50+30=80[/tex]
  • [tex]50-30=20[/tex]
  • [tex]50*30=1500[/tex]
  • [tex]50[/tex] ÷ [tex]30=1.66r[/tex]

___________________________________________________

So with this, we can conclude that each line has a similarity when we did:

  • [tex]cm[/tex] ÷ [tex]g[/tex]
  • [tex]=1.66r[/tex] (Repeating)

___________________________________________________

So the weight per [tex]cm[/tex] is [tex]1.66[/tex] or [tex]g*1.66r[/tex].
