    The number line shows the distance in meters of two divers, A and B, from a shipwreck located at point X: a horizontal number line extends from negative 3 to positive 3. The point labeled as A is at negative 2.5, the point 0 is labeled as X, and the point labeled B is at 1.5 Write an expression using subtraction to find the distance between the two divers. (5 points) Show your work and solve for the distance using additive inverses. (5 points) @geny55

    You added the amount of units A was away from zero bc that is where X is and then you added the amount away from x to B

    0 - 1.5=-1.5 2.5 - 0= 2.5

    A jar contains 0.75 liter of blackberry juice and 0.60 liter of blueberry juice. Patrick poured 0.25 liter of guava juice into the jar. He then drank 0.20 liter of the mixture. Part A: Write an expression to represent the total amount of juice left in the jar. (5 points) Part B: Identify which property is used in each step to simplify the expression. (5 points)

    at the first step, we have applied the associative property of addition, since we have wrote this: (0.75+0.60)+0.25=1.60

    The elevation of city A is 72 feet above sea level; the elevation of city C is 24 feet above sea level. The elevation of city D is 1 over 4 of the elevation of city C. Part A: Write an expression to represent the elevation, in feet, of city D. (5 points) Part B: Simplify the expression and explain why the answer is negative or positive. (5 points)

    Part A : D = (1/4) * C D = 1/4 * 24 D = 24/4 = 6 ft above sea level Part B : Your answer is positive because D is still above sea level...if it would have been below sea level, then it would have been negative

    The temperature of a city changed by −12 degrees Celsius over a 2-week period. The temperature changed by the same amount each week. Part A: Write an expression to show the average change in the temperature of the city each week. (5 points) Part B: Simplify the expression and explain, using words, what your answer means.

    you would have, t=-6w (temperature = -6 degrees multiplied by the week)you can simplify this to, -6=t/w which gives you negative six is equal to the temperature divided by the weeks
