When dividing two fractions, invert the second one and multiply the 2 top numbers and the 2 bottom numbers.
3/4 / 1/4 = 3/4 * 4/1 = 12/4 = 3
6x=18 (2x+5) x=6x+15. x-15=6x 5x=15 x=3
156 inches are in 13 feet
26< any number larger than 26 (whole numbers and fractions/decimals)
Y = 3/4x - 5/2....subtract 3/4x from both sides
-3/4x + y = -5/2 ....multiply everything by common denominator of 4
-3x + 4y = -10
