What is the ratio 20: 15 simplified

Which number line correctly shows 0.8 + 0.3?

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.

What is the slope of the line that contains the points (-5, 6) and (14. - 7)?
