It’s C. If you place the numbers from least to greatest, 126 (C) will be in the middle, or center.
Use cross multiplication so you have
7/x = 2/4
multiple 7 and 4 to get 28 and multiply x and 2 to get 2x and set them equal to each other
so your new equation is 2x=28 and then you just need to solve for x
The answer is x=14
hello :
the area of the circle is : 40 cm²
40 = <span>πr²
r² = 40/(3.14 )
r² = 12.73 cm</span>
What is the equation you are solving?
