O because both result in the equation 8X= 400, which simplifies to X = 5
O because both result in the equation 8x=400, which simplifies to x = 50
O because both result in the equation 40x=80, which simplifies to X = 2
O because both result in the equation 40x = 80, which simplifies to X = 20

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)
