10y=x because if you multiply your y by 10, you would get the x
4 3/4 =19/4=57/12
57/12 is larger than 38/12
Answer:
1/2n - 4 = 17
add four to both sides
1/2n = 21
n = 42
Step-by-step explanation:
The unknown number . . . . . (z)
The sum of the unknown number and 22 . . . . . (z + 22)
The sum of the unknown number and 22
divided by the same unknown number . . . . . . . (z + 22) / z
You said that quotient is 12. (z + 22) / z = 12
Multiply each side by 'z' : (z + 22) = 12 z
Subtract 'z' from each side: 22 = 11 z
Divide each side by 11 : 2 = z .
