Final answer:
The total mass of the recipe is 390 grams.
Step-by-step explanation:
To find the total mass of the recipe, we need to determine the mass of the pasta and vegetables separately and then add them together. The recipe calls for 130 grams of vegetables. Since the recipe requires twice as much pasta as vegetables, we can set up an equation to find the mass of the pasta. Let x be the mass of the pasta:
x = 2 * 130
x = 260 grams
Therefore, the total mass of the recipe is 130 grams (vegetables) + 260 grams (pasta) = 390 grams.
