4 is subtracted from five-sixths of w

Step by step

One sixth of the sum 1/6 ( + )
the sum of d and 3 1/6 (d+3)
minus the product 1/6 (d+3) - ( )( )
The product of 4 and q 1/6 (d+3) - 4q

The product of p and 3 3p
is subtracted from - 3p
three-fourths of s 3/4 s - 3p

three-fourths the sum 3/4 ( + )
the sum of 9 and k 3/4 (9+k)

Obviously, the final line in each case is the answer.

One sixths because 5-4=1 hope this helps

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
