£440 is divided between David, Mark & Henry so that David gets twice as much as Mark, and Mark gets three times as much as H
Lesechka [4]

Mark received £ 132

<em><u>Solution:</u></em>

Given that £440 is divided between David, Mark & Henry

Let "d" be the share of david

Let "m" be the share of mark

Let "h" be the share of henry

Total amount is 440

Therefore,

share of david + share of mark + share of henry = 440

d + m + h = 440 ------- eqn 1

<em><u>David gets twice as much as Mark</u></em>

d = 2m ----- eqn 2

<em><u>Mark gets three times as much as Henry</u></em>

m = 3h

h = \frac{m}{3}  ------ eqn 3

<em><u>Substitute eqn 2 and eqn 3 in eqn 1</u></em>

2m + m + \frac{m}{3} = 440\\\\\frac{6m + 3m + m}{3} = 440\\\\10m = 1320\\\\m = 132

Thus Mark received £ 132

What is standard form?
Katen [24]

Hey there! :)

When teachers ask you for the standard form in math, they are asking you to find the simplest form an equation with variables can be in.

Ax + By = C

Example : put y=2x -3 into standard form.

Subtract 2x from both sides.

-2x + y = -3 —> standard form.

Hope this helped! :)

Divide 1.20m in the ratio 2:3:4 in a clear way
tatuchka [14]
2:3:4 gives 9 equal parts.
1.20 divided by 9 is 0.133.

2 * 0.133 would be 0.266m
3 * 0.133 would be 0.399m
4 * 0.133 would be 0.533m

To check this calculate 0.533 + 0.399 + 0.266 would be 1.198m (close enough)

ANEK [815]
The volume would be 0.9 x 4.2

This means it is 90% smaller

Don't forget to round the nearest tenth place. That's the first decimal, so you answer should only have 2 digits.
