At a park, there are 38 people playing tennis some or playing doubles and some are playing singles there are 13 matches in progr

dmitriy555 [2]

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.

Pepsi [2]

Based on the number of pages read and the time it was read in, the number of pages read per day was <u>44 pages. </u>

Marion read 616 pages and did this in 14 days.

She read the same number of pages each day so the number of pages read per day was:

= 44 pages

In conclusion, she read 44 pages per day.
