<h3><u>Answer;</u></h3>

<em>16 half-cup servings of beans and 4 three oz. servings of shrimp</em>

<h3><u>Explanation and solution;</u></h3>

Let x = number of half-cup servings of beans  

Let y = number of 3 oz. servings of shrimp  

We will have 2 equations, one for carbs and one for calories  

7x + 9y = 148

30x + 190y = 1240  

30(7x + 9y) = 30(148)  

-7(30x + 190y) = -7(1240)  

210x + 270y = 4440  

-210x - 1330y = -8680

-1060y = -4240  

y = 4

7x + 9y = 148

7x + 9(4) = 148

7x + 36 = 148  

7x =  112

x = 16

Hence; X = 16 and Y= 4

16 half-cup servings of beans and 4, 3 oz. servings of shrimp

What conditions would cause an increase in the salinity of ocean water?
melisa1 [442]

The correct answer is high rates of evaporation.

There are lots of minerals and salts found in the ocean. Out of which the main component is sodium chloride. There are many of the ocean where there is less or no rainfall. The evaporation there removes the water from the ocean leaving behind lots of salts because of which the salinity of the ocean increases.
