Answer:X=20/3 y=17/3
Rainbow [258]4 years ago

Answer:

x=20/3 y=17/3

Step-by-step explanation:

1. x-y=1

2. 2x+y=19

The first equation can be rewritten as 2x-2y=2

We can then subtract the second equation from this:

2x-2y=2

2x+y=19

-3y=-17

y=17/3

Plug this into to solve for x:

x-17/3=1

x=17/3+1

x=20/3

A cubical swimming pool is of side 12m is filled with water up to a depth of 2m. What is the quantity of water in the pool in li
andrezito [222]

Volume is Length x Width x height.

The pool is cubical, so the length and width are the same dimension.

First find the volume of the pool that is filled by water:

Volume = 12 x 12 x 2 = 288 cubic meters.

Now convert cubic meters to liters:

1 cubic meter = 1,000 liters

288 x 1000 = 288,000 liters
