Answer:
21
Step-by-step explanation:
3/(x-3) = 8/(2x+6)
or, 3(2x+6) = 8(x-3) ( by cross multiplication)
or, 6x + 18 = 8x - 24
or, 8x - 6x = 24 + 18
or, 2x = 42
or, x = 42/2

Cat= 6kg
Dog = 6kg + 22kg
Total weight = 6kg + 6kg + 22kg
Total weight = 34kg
<span>601.2 rupees
You've been given the equation:
r = 62.4d - 210
I will assume that 62.4 is the actual exchange rate and that the 210 is a service fee of some sort for performing the exchange. So with 13 dollars, let's substitute that value into the equation and calculate:
r = 62.4d - 210
r = 62.4*13 - 210
r = 811.2 - 210
r = 601.2
So you'll get 601.2 rupees.</span>
Answer:
5:8
Step-by-step explanation:
Given: £90 is divided among Aahil, James and Merav in the ratio 1:3:5.
To find: How much Merav gets.
Answer:
Let's assume the shares of each to be 'x'.
This implies that 1x + 3x + 5x = 90.
9x = 90
x = 90/9
x = 10
Substituting this value of x in the ratio,
- 1 × 10 = 10 [<em>Aahil's share</em>]
- 3 × 10 = 30 [<em>James' share</em>]
- 5 × 10 = 50 [<em>Merav's share</em>]
Therefore, Merav gets £50.
Hope it helps. :)
