Giving it a try, on ipad it is difficult to draw model



D _______________________

A. [3u]-------430m------

B. []----480m----

C. [u]–300m–

So
2u = 300m + 480m
u = 390m

Total distance D = 3x390m + 430m
= 1600m
= 1km 600m

C. [____u_____]--300m--

So
2u = 300m + 480m
u = 390m

Total distance D = 3x390m + 430m
= 1600m
= 1km 600m

Hi

5 bags + 5 books = 3 kg 59g + 5 kg 36g = 8kg 95g = 8095 g
1 bag + 1 book = 1619 g

4 bags + 2 books = 5 kg 36g = 5036 g
2 bags = 5036 - 2 x 1619 = 1798, 1 bag = 899 g
8 bags + 5 books = 3 x 899 + 5 x 1619 = 10792 = 10kg 792g

cheers.

Pls help me on this P3 question; Thanks!

A box can be filled either with 21 big balls or 49 small balls.
If there are already 35 small balls in the box, how many big balls can still be placed in the box?

The space for putting the big balls and small balls ratio is

For every 7(49) small balls, it can accomodate 3(21) big balls.

49-35 = 14 small balls space available.

14 small balls space can accomodate 6 big balls.

Hence 6 big balls can be placed in the box.
