1 block weighs 8kg + half a block
half a block weighs 8kg
1 block weighs 16kg
hence, 1 and a half blocks weighs 16+16/2 = 24kg
ok, suppose a block weighs x kg
Then x = 8 + 0.5 x meaning that 0.5 x = 8 meaning x = 16
The question says, how much does 1.5 blocks weigh,
well 1.5*x = 1.5 * 16 = 24
This might be easier for you to visualize,It says the answer is 24, but I'm still stuck at 18...
If 1 block weighs 8kg + half a block, then how can 1/2 a block weight 8kg?
It should be 8kg+4kg = 12kg
1/2 of 12kg = 6kg + 12kg(one block) = 18kg
1 block = 1/2 block + 1/2 block
1 block = 8kg + 1/2 block
ok, suppose a block weighs x kg
Then x = 8 + 0.5 x meaning that 0.5 x = 8 meaning x = 16
The question says, how much does 1.5 blocks weigh,
well 1.5*x = 1.5 * 16 = 24
1 block = 1/2 block + 8kg
subtract 1/2 block from both sides
1/2 block = 8kg
multiply both sides by 2
1 block = 16kg
You need to find the weight of 1-1/2 block.
1block * (1.5) = 16kg * (1.5)
1.5 blocks = 24kg
