The least common multiple is 60
Speed of Bob = 5/1.25 = 4miles/h
Speed of Stan = 3/ (5/6) = 3 * 6 / 5 = 18/5 = 3.6 miles/ h#
Bob runs faster than Stan
Remember that
A statistical question is a question that can be answered by collecting data that vary.
so
Classify
Hw tall are the memmbers of my class? -------> Is a statistical question
How tall am i? --------> is a nonstatistical question
How old are the students in my school? -------> Is a statistical question
A statistical question can be measured and controlled, while a nonstatistical question cannot provide for the measurement.
Your answer is 54, the drawing is a bit wrong because I did the prime factor tree of 54 wrong, so you'd do 2 × 3 × 3 × 3 which is 54.
1/2(5x + 12) = 2x - 3
5/2 x + 6 = 2x - 3
5/2 x - 2x = -3 - 6 = -9
5x = 2 x -9 = -18
x = -18/5
