  1. If Kayla has a red ribbon with length 25  9 m and piece of 5 7 m is cut from it and gave to Sania . Find how much long ribbon left with her?                                                                                                                                                                                                                      
  • Kayla has a ribbon of length = 25 9 m.
  • Part of ribbon give to Sania = 5 7 m.
  • So, the length of the ribbon left =25 9 m - 5 7 m = 175  63 = 130  63 m
  • So , the ribbon left with Kayla is 2.06 m .

If the pattern continues, it could be 2.75 * 63.63 repeating to get to the end of the card. The second answer is 63. When she started the card, she had $175. Divide 175 by 2.75 and you get 63 repeating.

Igoryamba

Answer:

e.29 d.1

Step-by-step explanation:

  • x+30<60 :

we will replace with the values we have :

  • 300 that's a big number . Obviously it isn't a solution
  • 50 : 30+50 = 80>60 so no
  • 45: 30+45= 75 >60  so no
  • 30+30 = 60 we have < not ≤ so no
  • 1 yes . it's obvious
  • 29 +30 = 59<60 so yes !
