50 points hannah is 2 times her sister’s age. the sum of their ages is no more than 18 years. 1) write an inequality that can be used to represent this situation. 2) using the inequality you just found, solve it to find the oldest age hannah's sister can be.

Step-by-step explanation:

Let "Hannah" = h, and her sister = s

h = 2s

h +  s ≤ 18

Plug in 2s for h in the second equation.

(2s) + s ≤ 18

Simplify

2s + s ≤ 18

3s ≤ 18

Isolate the variable (s). Divide 3 from both sides

(3s)/3 ≤ (18)/3

s ≤ 18/3

s ≤ 6

2) The oldest Hannah's sister can be is 6 years

~

- 70

this is the answer for you hope it
