Answer:

x = 4

BC = 20

Step-by-step explanation:

From what we have, the measures EF = FG = GH

That means;

AB = CD

Thus;

5x = 2x + 12

5x - 2x = 12

3x = 12

x = 12/3

x = 4

BC = AB = CD = 5(4) = 2(4) + 12 = 20

If you can buy 1⁄3 of a pound of turkey for 4 dollars, how much can you purchase for 10 dollars? Write your answer as a fraction

Hey Shardj16!

The correct way to answer your question would be to:
Let t be the variable for the pound of turkey.
Write down the equation first: 1/3t = 4
Now you must get the 4 to 10, so you multiply it by 2.5!
2.5/3=10
You can make 2.5/3 into a fraction by multiplying the numerator and denominator by 2, turning it into 5/6.
The correct answer to your question would be 5/6 pounds of turkey.

Hope I was able to help! If you need any more help, please let me know.
