Select all the equivalent expressions by combining like terms.

5.2x + 8 + 21x - 3

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2

What is the least common multiple for 6 and 8? what is the least common multiple for 4 and 12 ? what is the least common multiple for 11 and 12? what is the least common multiple for 3 and 6?

Subtract and simplify. (-y^2 – 4y - 8) – (-4y^2 – 6y + 3) show how you got the answer if your answer is right i will mark you
