Answer:

The system of inequialities is:

  • g ≤ 8
  • g ≤  3k-30

Step-by-step explanation:

Hi, we have to write the inequalities using the information given:

k: Kyle’s age

g: Kyle’s grandmother’s age

a-: Kyle´s grandmother is not more than 80 years old.

Not more means less or equal (≤), mathematically speaking:

g ≤ 80

b-: Kyle´s grandmother’s age is, at most, 3 years less than 3 times Kyle´s age.

At most also means less or equal.

g ≤  3k-3

The system of inequalities is:

  • g ≤ 8
  • g ≤  3k-30

Feel free to ask for more if it´s necessary or if you did not understand something.

I would say it would look something like this: 3k - 3 = g? That would be my best guess. I hope I helped & I'm so sorry if I'm wrong!
