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 :)
3/8 beacuse you would change that to a mix number
Combine like terms so 3x + 3x= 6x
Then put the minus signs with the 4 and 5 and add them together so -4+ -5= -9
Now you have 6x=-9 So you divide by 6 on both sides canceling out 6
but 9 divided by 6 doesn't go into a specific number therefore it has no solution which is a possible answer
When the circle is shaded it means that the variable is equal or greater or it equal or less
So 1(1/3) turns into 4/3 because you multiply denominator by 1 the whole number then add 1 to that so its 4/3 × 5/8 the numerators multiply to 20 and denominators multiply to 24 so its 20/24 which simplifies to 10/12 then to 5/6
