In the figure, cd = ef and ab = ce. complete the statements to prove that ab = df.
cd + de = ef + de by the property of equality.
ce = cd + de and df = ef + de by .
ce = df by the property of equality.
given, ab = ce and ce = df implies ab = df by the property of equality.

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
