A 2010 estimate of Australia's population is 21,515,754. Which is the best estimate of the number of Australians with type AB blood in 2010?

Itook a better photo of the question so y’all can see it i hope it’s a fine photo

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
