if triangle bts= ghd ,bs=25, ts=14, bt=31, gd=4x-11, m < s=56, m < b=21, and m < h= (7y+5), find the values of x and y

Acertain population of bacteria demonstrates exponential growth doubles in size every 4 days. how long will it take the population to triple in size?

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Solve 3x-18=2y and 5x-6y=6 by elimination show work
