Question

Help pleaseeeeeeeeeeeeee and write it descriptively

Answer 1

14)
`(1)/(2) n-1` (half of n is
`(1)/(2) n` and subtract that with 1)

15) 3o+4 ( multipy o with 3, it becomes "3o" and add that with "4")

16) 5p-2 (same concept as No.15)

17) 7+r ( add 7 with "r")

18) s+7 (same concept with No.18)

19) t-10 (subtract 10 from "t")

20) 10-u ( subtract "u" from 10)

21) 2v ( multiply 2 with v)

22) 2w (same concept as No.21)

23)
`(x)/(5)` (divide x with 5 and show the result in fractions)

24)
`(5)/(y)` ( divide 5 with y and show the result in fractions)

Tip : Alphabets and numbers never combine unless you multiply them with it (eg. 3*x = 3x) but ( 3+x stays like that ).
