Answer: 761 yd
split the figure into different pieces to make it easier
(23 x 7) + (40 x 15)
161 + 600
761
hope this helped :)
If we let
be the number of pages read in 1 hour, then in 7 hours Doug reads
pages. We know that this number of pages is 231, so we have

Answer: There is one solution to the given equation.
Step-by-step explanation: We are given to find the number of solutions to the following equation :

Since the given equation is linear in one variable x, so it will have only one solution.
The solution of equation (i) is given by

Thus, there is one solution to the given equation.
