Answer:
2 and 4
Step-by-step explanation:
Try out 2/3 in each equation.
1. 2/3 + 12 120
12 2/3 120 is not true, so its not this one
2. 2/3 + 12 [tex]\leq[/tex] 120
12 2/3 [tex]\leq[/tex] 120 is true, so this one works!
3. 12*2/3 [tex]\geq \\[/tex] 120
8 [tex]\geq[/tex] 120 is not true, so this one doesn't work
4. 12 * 2/3 [tex]\leq[/tex] 120
8 [tex]\leq[/tex] 120 is true, so this one works
