Answer: The answer is 5 and 3/5 hours
Step-by-step explanation:
117+114= 231
360-231= 129
Now find two numbers that add up to 129
Answer:
1 2/7
-138/7
use l.c.m . Or multiply through by 30.
2/5 ≤ x-4
0.4 ≤ x-4
let's just add 4 on both sides
0.4 +4 ≤ x-4 +4
4.4 ≤ x
simple as that. just handle inequalities like you would handle equations
280
each individual line is a +20, therefore one line before 300 would be 300-20=280
