Cassandra works at a bookstore. yesterday, she sold 18 hardcover books. the rest of the books she sold were paperback books. she sold a total of 41 books. how many paperback books did she sell? use the variable p to represent the number of paperback books cassandra sold yesterday. which equation represents this situation and its solution? 18p = 41; p = 23 p + 41 = 18; p = 23 41p = 18; p = 23 p + 18 = 41; p = 23

The trigonometric ratios sine and secant are reciprocals of each other

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
