It is not correct because if you simplify 10/4 it comes out to 5/2 therefore 5/2=5/2.
Beth and May run the same amount.
Step-by-step explanation:
2√48= 13.86
3√147= 36.37
Perimeter: 13.86+13.86+36.37+36.37= 100.46

To divide by 1/2, multiply by 2/1:
3 2
-- * ---
7 1
Multiplying, we get 6/7.
1/2x + 42 = 4x
-1/2x -1/2x
------------------------
42 = 3.5x
/3.5 /3.5
------------------------
12 = x
the number is 12
explanation: 42 more than 1/2 of a number can be written as 1/2x + 42
four times a number can be written as 4x.
42 more than 1/2 of a number is equal to 4 times a number. So 1/2x + 42 = 4x.
Hope this helps :)
