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.
Answer:
x - 3 > = 5
x > = 5 + 3
x > = 8
closed circle on 8...because of the equal sign.....shaded to the right...because of the > sign.
Step-by-step explanation:
Answer:8x + -4 > 12
8x > 16
x > 2
