Five less than three times the length l

The expression could be written as: 3L-5.

Step-by-step explanation:

We are asked to find an variable equation/ expresssion for the following world problem:

      " Five less than three times the length L".

for this we have to firstly take '3' times the length  'L' (i.e. 3L) and then subtract that expression by 5 to make it five less than three times the length 'L' and hence obtain our required expression.

Hence, the expression is represented as:  3L-5

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
