2n - 9
Step-by-step explanation:
Let the number be n. Then "a number multiply by two then subtract 9" yields
2n - 9
X = number of singles matches
y = number of doubles mnathes
so we have the equation x + y = 13.......(1)
also
2x + 4y = 38 ...........(2)
(1) and (2) are the required equations
b) Find how many maches are in progress by solivng the above equations:-
x + y = 13 multiply this by -2:-
-2x - 2y = -26
2x + 4y = 38 Adding to removes the terms in x:-
2y = 12
y = 6
so x = 13-6 = 7
So the answer is 6 double matches and 7 singles are in progress.
You would start at (0,36) and then move to (1, 24) , (2,12), (3,0) because he gives out 12 bags per hour
