Acaterer needs to buy 21 pounds of pasta to cater a wedding. at a local store, 8 pounds of pasta cost $12. how much will the caterer pay for the pasta there

31.5 $

Step-by-step explanation:

First lets se how much 1 pound of pasta costs in the store. We do this dividing the price for 8 pounds over those 8 pounds:

12/8 = $1.5 each pound

As 21 pounds are needed:

$1.5 * 21 = $31.5

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
