Answer:
x = 20
Step-by-step explanation:
5x + 9 + 3x + 11 = 180
Combine like terms
8x + 20 = 180
Subtract 20 from both sides
8x = 160
Divide both sides by 8
x = 20
The approximate probability of randomly choosing one vegetable and one grain-based side dish is: d. 0.33333
<u><em>Explanation</em></u>
Vegetable side dishes = 3, Fruit side dishes = 2 and Grain-based side dishes = 5
So, total number of side dishes
Number of ways for choosing two side dishes from total 10 dishes will be :
We need to randomly choose one vegetable and one grain-based side dish, so the number of ways
Thus, the probability
100,000,000 + 50,000,000 + 3,000,000 + 400,000 + 700 + 80
