If your friend already read 150 pages and reads 20 pages a hour and you just started the book and read 30 pages an hour, how long will it take you to catch up to your friend

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

Right ∆abc has coordinates a(-7, 3), b( -7, 10), and c(-1, 3). the triangle is reflected over the x - axis and then reflected again over the y - axis to create ∆a'b'c'. which are the coordinates of vertex a'?

Point a (7,3) is translated to a'(16,-9). which rule describes the translation?
