£150 is divided between Malachy, Paul & Brian so that Malachy gets twice as much as Paul, and Paul gets three times as much

Dmitry_Shevchenko [17]

Answer:

£90

Step-by-step explanation:

Let M = Malachy's share

and P = Paul's share

and B = Brian's share.

We have three conditions:

(1) M = 2P

(2) P = 3B

(3) M + P + B = 150

Solve for B:

Substitute (2) into (3) (4) M + 3B + B = 150

(5) M + 4B = 150

Substitute (2) into (1) M = 2(3B)

(6) M = 6B

Substitute (6) into (5) 6B + 3B + B = 1 50

(7) B = 15

Solve for P:

Substitute (7) into (2) P = 3×15

(8) P = 45

Solve for M:

Substitute (8) into (1) M = 2×45

M = 90

Malachy gets £90.

to make applesauce you need 2 cups of sugar for every 16 apples use the ratio table to find out how many cups of sugar you need

expeople1 [14]

For this case we are going to define the following variables:
x: number of cups of sugar
y: number if apples
We then have the following relationship:
$\frac{x}{y} = \frac{2}{16}$
For 4 apples we have: $\frac{x}{4} = \frac{2}{16}$
From here, we clear the value of x.
We have then:
$x = 4 \frac{2}{16}$
$x= \frac{8}{16}$
$x= \frac{1}{2}$
Answer:
you need 1/2 cups of sugar if you have 4 apples
