44 × 20 × 10 = 440 × 2. but is it true or false ?
Vinil7 [7]
If you would like to know if 44 * 20 * 10 equals to 440 * 2, you can check it like this:

44 * 20 * 10 = 440 * 20 = 8800
and
440 * 2 = 880

So, the correct result is False, because 8800 is not equal to 880.

Alchen [17]
The rate a computer works is 1/time. Working together, you add the rates.
Let new computer be x, old computer be y.
x = y - 7

\frac{1}{x} + \frac{1}{y} = \frac{1}{13} \\  \\ \frac{1}{y-7}+\frac{1}{y} = \frac{1}{13} \\  \\ \frac{2y-7}{y(y-7)} = \frac{1}{13} \\  \\ y(y-7) = 13(2y-7) \\  \\ y^2-33y+91 = 0 \\  \\ y = 29.96 \\  \\ x = y-7 = 29.96-7 = 22.96
Rounded to nearest tenth gives:
x = 23 hours
