If 1 brick and 1/2 a brick together weigh 1 kg, what is the weigh of two whole bricks in kilos

4/3 kg

Step-by-step explanation:

Let x represent a half brick, let y represent a 1 brick.

We know that 1 brick and 1/2 brick weigh 1 kg. so we represent this as

We know that obviously x is half of y. so

Subsitur this for x.

This means one block weight 2/3 kg. So how much 2 weigh.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
