Answer to Q73

If a brick weighs 3kg plus half of a similar brick. How much does a brick and a half weigh?

If a brick weighs 3kg plus half of a similar brick, we can write this as an equation:

Let brick weight be x, so

x = 3kg + ½x

We can now find x

x = (6+x) ÷ 2
2x = 6+x
x = 6kg

So a brick weighs 6kg

How much does a brick and a half weigh?

Now since a brick weighs 6kg, half a brick will weigh 3kg

So, a brick and half will weigh 6 + 3 = 9

Answer: 9kg
