Answer:

x= -2

Step-by-step explanation:

-2x-7=3(4x+7)

multiply numbers in parenthesis by 3

-2x-7=12x+21

move terms

-2x-12x=21+7

subtract -2x to -12x but since there negative the equation is addition. Also, add 21 to 7

-14x=28

divide both sides by -14

x= -2

How many servings are in 12 cups of rice a.
Alex777 [14]
     One serving is 3/4 cups of rice. To find out how many serving there are in 12 cups of rice, you divide 12 by 3/4. (When dividing fractions, don't ask why. Flip the second one over and multiply).
   12/(3/4) = 12 *(4/3) = 48/3 = 16
     There are 16 servings of rices in 12 cups.
