First, you need to have j on it own. Since j is over 4-8, you times both sides of the inequality so the /4-8 is canceled.
Your new inequality equation is j<4(4-8). Solve the bracket and then times the answer by 4.
~ j<4(-4)
~ j<-16
We know that 1 foot is 12 inches then, we change all quantities to inches to ease the calculations:
5 ft 9 in = 5(12) + 9 = 60 + 9 = 69 inches
10 ft 11 in = 10(12) + 11 = 120 + 11 = 131 inches
so we add:
<span>5 ft 9 in + 10 ft 11 in
= 69 inches + 131 inches
= 200 inches
if we want the result in foot we divide:
= 200/12
= 100/6 = 50/3
= 16 ft 8 in</span>
