How many years will it take for a person in the United States eat 1,120 pounds of turkey (14 pounds)
Liono4ka [1.6K]
If I understand you, a person eats about 14 pounds of turkey a year.  So we will divide all that turkey (1120 pounds) by 14 to find out how many years.

1,120 ÷ 14 = 80   So it will take 80 years.   (Since babies can't eat that much turkey a year it will actually take more than 80 years - or the person can eat more than 14 pounds in some years to make up for their early years when they ate less)  I know it's a math question, but I also like to be realistic about it.  Who measures the amount of turkey they eat yearly anyway?  :-)

fredd [130]

Answer:

Step-by-step explanation:

5x + 7x - 1/2x + 1/4 = 6

move x to one side move numbers to the other side

5x + 7x - 1/2 x = 6 - 1/4

add x and numbers

23/2x = 23/4

divide both side by 23/2

x = (23/4)/(23/2)

  = 1/2

plug it in to check the answer

5/2 + 7/2 - 1/4 + 1/4 = 6

12/2 = 6

What number could be added to 0.40 mL for the level pf precision to be 0.01mL?
Mila [183]

Answer:

-0.39mL

Step-by-step explanation:

Let x be the number.

The expression would be: 0.40 + x = 0.01

Apply algebra to the equation to solve for x. You can subtract 0.40 from each side to simplify the expression. Here's what it should look like after applying algebra: x = -0.39

Therefore the answer is -0.39mL
