I think its is 4/5 but not positive
Answer:
Option 4: r ≥ 6
Step-by-step explanation:
5(6+3r) + 7 ≥ 127
30 + 15r + 7 ≥ 127
37 + 15r ≥ 127
15r ≥ 90
r ≥ 6
Ok so first multiply 4 by .25 to get 1 then 1 by 2.36 to get 2.36
This makes it easier because multiplying by 1 is easier then by a number with decimals
The possibile answer is 10 ÷ 6 = 1.6
