What is the numerical expression 1/3 + 4/9 (3 + 1/2) - 1/2 ?

Element x decays radioactively with a half life of 8 minutes. if there are 450 grams of element x, how long, to the nearest tenth of a minute, would it take the element to decay to 37 grams?

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.

The equation of line wx is y=2x-5. write an equation of a line perpendicular to line wx in slopeintercept form the contains points (-1,-2)
