Mass box A=10grams Mass box B=5 grams; Mass box C -made of one A and one B How many grams of B would it take to combine with 20 grams of A? square grams

To solve this problem, we need to determine how many grams of box B would be required to combine with 20 grams of box A.<br /><br />Given:<br />- Mass of box A = 10 grams<br />- Mass of box B = 5 grams<br /><br />We are asked to find out how many grams of B are needed to combine with 20 grams of A.<br /><br />Since each box A has a mass of 10 grams, 20 grams of A would mean we have 2 boxes of A (because \( \frac{20 \text{ grams}}{10 \text{ grams/box}} = 2 \text{ boxes} \)).<br /><br />Now, if we want to combine these 2 boxes of A with an equivalent number of boxes of B, we need 2 boxes of B as well. Since each box B has a mass of 5 grams, the total mass of 2 boxes of B would be:<br /><br />\[ 2 \times 5 \text{ grams} = 10 \text{ grams} \]<br /><br />Therefore, it would take 10 grams of B to combine with 20 grams of A.<br /><br />The answer is \(\boxed{10}\) grams.
