5. A biologist recorded the population growth of two species of frogs in a pond area starting in 2010. The first species started with 42 frogs and
increased by 6 frogs per year. The second species started with 30 frogs and
increased by 8 frogs per year.
A. Write an equation modeling equal populations of the frogs t years
after 2010.

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9

Sum is 17 and their difference is 3

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.
