A student’s work is shown below. y – 12.7 = 32.75

y – 12.7 – 12.7 = 32.75 – 12.7

y = 20.05

Which is the best statement about the student’s work?

The student solved the problem incorrectly. The student should divide both sides of the equation by -12.7 to create a zero pair.
The student solved the problem incorrectly. The student subtracted incorrectly because 32.75 – 12.7 is 20.68.
The student solved the problem incorrectly. The student should add 12.7 to both sides of the equation to isolate the variable, y.
The student solved the problem correctly. Subtracting 12.7 from both sides of the equation isolates the variable, y.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.

The equation ip| = 2 represents the total number of points that can be earned or lost during one turn of a game. which best describes how many points can be earned or lost during one turn?
