You need to make an inequality. You know 5 pounds will serve 14 people but you don't know how much you need to serve 49 people so you need to set up the equation \frac{5}{14} * \frac{x}{49} . You then cross multiply to get 14x=245. Finally you divide 14 on both sides to get x=17.5 lbs of pasta salad

A given line has the equation 10x + 2y = −2.
stepladder [879]
10x + 2y = -2

2y = -10x -2

y = -5x - 1 (slope is -5 and a parallel line will have the same slope)


y = mx + b

slope(m) = -5

12 = -5(0) + b

12 = 0 + b

12 = b

so the parallel line is y = -5x + 12

hope this helps, God bless!

Answer:

I believe it is distributive because you are finding the products. Yes, the numbers are mixed up but the parenthesis often involve distributive property.
