You are given a length in yards, a length in feet and inches, and you need an answer in inches.
The first step is to convert yards into inches and the length in feet and inches also to inches.
1 yd = 36 inches
2 1/2 yd = 2 1/2 * 36 in.
2 1/2 yd = 90 in.
She bought 90 in. of ribbon.
1 ft = 24 in.
2 ft 8 in. = 2 * 12 in. + 8 in. = 24 in. + 8 in. = 32 in.
She had 32 in. left.
90 in. - 32 in. = 58 in.
She used 58 inches.
Micah's end result is incorrect.
He added the rational expressions correctly, but then incorrectly "simplified" the sum. The sum (x²+x-4)/(x²+3x+2) cannot be simplified further.
He takes 30 minutes in 3 breaks.
( 3 breaks = 10 mins each)
So 10, 10, 10} 3 x 10 equals 30.
