Question

The weight of chemical A is 6.29 grams more than that of chemical B. If chemical A weighs 17.3 grams, chemical B weighs how many grams?

a) 10.01
b) 11.99
c) 10.51
d) 17.3

Answer 1

The weight of chemical B is 11.99 grams.

Let's denote the weight of chemical B as x grams. According to the given information, the weight of chemical A is 6.29 grams more than that of chemical B. Therefore, the weight of chemical A can be expressed as x + 6.29 grams.

The problem states that the weight of chemical A is 17.3 grams. So, we can set up the equation:

x + 6.29 = 17.3

Now, let's solve for x:

`\[ x = 17.3 - 6.29 \]`

`\[ x = 11.01 \]`

Therefore, the weight of chemical B is 11.99 grams.

In summary, if chemical A weighs 17.3 grams and is 6.29 grams more than chemical B, then chemical B weighs 11.01 grams. So, the correct answer is not among the provided options.
