Five pounds is equal to 2.268 kilograms. How many kilograms is 2 pounds?
Tema [17]

Given:

5 pounds = 2.268 kilograms

To find:

The number of kilograms in 2 pounds.

1 pounds = \dfrac{2.268}{5} kilograms

1 pounds = 0.4536 kilograms

Multiply both sides by 2.

2 pounds = 2×0.4536 kilograms

2 pounds = 0.9072 kilograms

Therefore, the correct option is B.

Work out the value of x
zalisa [80]

Answer:

x = 67.5°

Step-by-step explanation:

A circle's angles add up to 360°

So,

x+3x+90 = 360

4x+90 = 360

4x = 360-90

4x = 270

Dividing both sides by 4

x = 67.5°
