Let unknown number be x.
Given,
7x - 8 = 3x + 4
4x = 12
x = 3
Hence, the number is 3.
X=90 which (180-90) is 90 for m and n

Answer:
9 hr * 60 min/hr = 540 min. 540 min * 60 sec/min = 32,400 sec. Use the method described by panic mode: round the number down until there is only one non-zero digit left. Here, 32,400 rounds down to 30,000. Now count the number of zeroes; the result is the order of magnitude: 4. (You see this in scientific notation also: 30,000 = 3 × 10^4.)
