Age questions are common in P5 . So assumed to be P5 standard.

Swift Formula:

4x + 21.90 = 7x - 16.50

3x = 38.40
x = 12.60

12.60 x 4 + 21.90
= 50.40 + 21.90
= 72.30

Meh .
x = 12.80

12.80 x 4 + 21.90 = 72.30

Calculation error =(
Did it in a squeezy bus lol .

lego:

I just got my mobile changed to M1 recently. The port over for mobile takes only a few hours, it is done late at night with minimum disruption to service.


It's the internet fibre broadband that I have a problem porting over to M1. I understand that all fibre broadband installation is done by 3rd party -Netlink Trust, not M1.
My initial appointment with Netlink Trust was cancelled because of some \"insufficient capacity\" issue and I was told that it can take up to 40 days for them to fix it. As of today, I am still waiting for it to be resolved. :sad:

U can't port over internet .
There's no number or line to be used .
It's just cancellation of the broadband of your original ISP and new service installation by m1 and opennet staffs .

Duration and time can be in the same statement .

Timeline is always recommended as it gives a clearer idea of the whole question .

Hi it is a very common question.

Can u draw a table ? Diagram ?
If u need further explanation , i can do it on Skype .

Hi, I need an advice on the following question. My dd used 2 methods to solve the questions. However, there seems to have some discrepancies in the answer.


1) the area of big triangle minus off the area of small rectangle - 48cm2.
2) the area of the rectangle + 2 sets of area of the little triangle shown. - 30cm2.

Anyone can explain why is there the discrepancy?

Thanks.

If the triangles are proportionate, that 3cm would be 6cm instead.

4x + 21.90 = 7x +16.50

3x = 38.40
x = 12.60

12.60 x 4 + 21.90
= 50.40 + 21.90
= 72.30

466 - 230 = 236

236 ÷ 2 = 118
118 x 3 = 354

Amber had 360 more beads than Lynn at first. On monday

, after they had each use 1/3 of what they had, the number of lynn's beads became 25% of Amber's. On tuesday, after Amber gave some beads to Lynn, the number of Amber's beads became 60% of Lynn beads.
a) How many beads Lynn used on aMonday?
b) How many beads did Amber give to Lynn on Tuesday?

Please help me to solve thk u..

Draw a model .
1. Amber = Lynn + 360 ....so Lynn = 1unit , Amber = 1 unit + 360 .
2. After using 1/3 , Draw another set of model to show 2/3 left .
3. 2/3 unit = Lynn , 2/3 unit + 2/3 x 360 = Amber .
4. At this point Lynn = 1/4 of Amber , 25% to 100% , 1 : 4 .
5. Form an equation from the 3 and 4 and solve .
6. No change in total number of marbles . Amber become 60% and Lynn 100% so ratio is 3:5 .
7. compare 5 and 6

Hi,

Can someone help to answer this question with a model?

Jane bought 4 similar tins of paint and 3 similar brushes for $54. Mary paid $106 for 8 similar tins of paint and 5 similar brushes. Find the cost of a tin of such paint.

Thanks.

This is solving by elimination method . Make either 1 the same , so they cancel out each other . Then u left with some value and another unknown .
