A, r=9

Step-by-step explanation:

Multiply through by the LCM

r + (3×5) <= 3×8

r + 15 <= 24

r <= 24 - 15

r <= 9

r=9

Step-by-step explanation:

have a nice day

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
