Answer:

0---22.5   and    21---36

Step-by-step explanation:

you will always have 21 free CDs so you can put a closed circle on 21 then you can have a max of 15 CDs (180/12) soo put another closed circle on 36

now time for tapes, which is easier, the minimum is 0 and the max is 22.5. Now put closed circles on each and you're done. Except that .5 might get you in trouble, use your own discretion on rather to leave it on the .5 or round. I don't know what your teacher is looking for so I will let you decide.

Law Incorporation [45]

Answer: 1967

Step-by-step explanation:

Ada was 15 years when her sister Ngozi was 18 years.

This means that Ngozi is older than Ada by:

= 18 - 15

= 3 years

If Ngozi is older by 3 years, this means that she must have been born 3 years earlier than Ada

If Ada was born in 1970, Ngozi was born:

= 1970 - 3

= 1967
