Using the sum (addition) and two 2-digit addends, 12 + 34 can be answered without regrouping.
He drove 219.375 miles more on the fist day than the second day.
Andy will record 6x + 5 bacteria cells, while Samantha will record 2^x + 3 bacteria cells. These will be equal at a time when:
6x + 5 = 2^x + 3
Plotting both of these shows that they are equal when x = 5 and y = 35.
Therefore, the number of bacteria cells will be equal at 35, at t = 5 hours.
Xy + yx+ x - 3x - 3y
xy + yx + -2x + 3y
