Answer:

1. -19x

3. 23 -  8x

5. -18x + 2y

2x - 22x = -20x

-20x + x = -19x

second one:

12x - 20x = -8 x

23 - 8x

third:

3y - y = 2y

-18x + 2y

¿Cuántos litros de agua se precisa para llenar una piscina inflable de 1/4 de metro cúbico?
8_murik_8 [283]

Answer:

250 litters

Step-by-step explanation:

To solve this question, we first need to know the conversion from cubic meter to liter.

1 cubic meter is equal to 1000 liters.

So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:

1 m3 -> 1000 L

1/4 m3 -> x L

x * 1 = (1/4) * 1000

x = 1000 / 4 = 250 L

So we need 250 liters of water.
