Answer:
t ≥ 0
Step-by-step explanation:
3/10(t+2)-t/20 ≥ 3/5
Expand brackets.
3/10t + 6/10 - 1/20t ≥ 3/5
Add -6/10 on both sides.
3/10t + 6/10 - 1/20t - 6/10 ≥ 3/5 - 6/10
3/10t - 1/20t ≥ 3/5 - 6/10
Combine like terms.
1/4t ≥ 0
Multiply both sides by 4/1.
1/4t × 4/1 ≥ 0 × 4/1
t ≥ 0
Answer:
t≥0
Step-by-step explanation:
[tex]\frac{3}{10} (t+2)-\frac{t}{20} \geq \frac{3}{5} \\L.C.M. ~of~10,20,5=20\\multiply~by~20\\6(t+2)-t\geq 12\\6t+12-t\geq 12\\5t\geq 12-12\\5t\geq 0\\t\geq 0[/tex]
