A balance scale is perfectly balanced with two blocks on one side and ten weights on the other. If each weight equals 2.0 grams, how much does one block weigh?

(2*10)/2 = ?

10 pounds

10

211

10

10 pounds

To find out how much one block weighs, we need to do some simple math. Here's how you can do it:

1. First, determine the total weight on the weighted side of the balance scale. We know that there are 10 weights, and each weight equals 2.0 grams. So, the total weight on the weighted side is:

10 weights * 2.0 grams/weight = 20 grams

2. We also know that the other side of the balance scale is perfectly balanced with two blocks. Since the scale is perfectly balanced, the total weight on this side must be the same as the total weight on the other side. Therefore, the total weight on the side with the two blocks is also 20 grams.

3. To find out the weight of one block, divide the total weight on that side by the number of blocks:

20 grams / 2 blocks = 10 grams

Therefore, each block weighs 10 grams.
