27/73 is in its simplest form.
Simplify the fractional part, and then rewrite it with the integer part in front. For example, if asked to simplify 715/25, all you need to do is to simplify 15/25 = 3/5. The answer, then, is 73/5.
To express 73 percent as a fraction in its lowest terms, we first convert 73 percent to a fraction by dividing it by 100. This gives us 73/100. To reduce this fraction to its lowest terms, we find the greatest common divisor (GCD) of 73 and 100, which is 1. Therefore, 73/100 is already in its lowest terms.
9x - 2y = 73 . . . . . (a) 5x - 9y = 9 . . . . . (b) (a)*9: 81x - 18y = 657 (b)*2: 10x - 18y = 18 Subtract: 71x = 639 so x = 9 Substitute in (a): 81 - 2y = 73 2y = 8 so y = 4 The ordered pair is (9, 4)
You really should ask these questions separately, but.... 3x2 - 18x = 0 ∴ (3x)(x - 6) = 0 ∴ x ∈ {0, 6} x2 - 10x + 24 = 0 ∴ (x - 6)(x - 4) = 0 ∴ x ∈ {4, 6} 2x2 - 3x = 8 ∴ 4x2 - 6x = 16 ∴ 4x2 - 6x + (3/2)2 = 16 + (3/2)2 ∴ (2x - 3/2)2 = 16 + 9/4 ∴ 2x - 3/2 = (73/4)1/2 ∴ 2x = 3/2 ± √(73/4) ∴ 2x = (3 ± √73) / 2 ∴ x = (3 ± √73) / 4 ∴ x ∈ {(3 - √73) / 4 , (3 + √73) / 4}
