    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)

    so I think you mean to say 2.5

    the distance from -2.5 to 0 is 2.5 the distance from 0 to 1.5 is 1.5 the distance between -2.5 and 1.5 is the sum of the distances from -2.5 to 0 and 0 to 1.5

    I thought you were looking for distance what is the negative number there for?

    to represent the A distance from the ship wreck

    A = -2.5 B = 1.5 - 2.5 - 1.5 = - 4 This number is also known as the opposite (number), sign change, and negation. so by using addictive inverse i am basically changing the 1.5 into -1,5 so, - 1.5 + - 2.5 = - 4

    anyways the distance from -2.5 to 0 can be found by doing 0-(-2.5) and the distance from 0 to 1.5 can be found by doing 1.5-0 and the distance from -2.5 to 1.5 can by found by adding those distances \[(1.5-0)+(0-(-2.5)) \\ (1.5)+(-(-2.5)) \\ 1.5-(-2.5)\] we have written the subtraction expression they seeked

    we can write it to an equivalent addition expression by using the fact that -(-2.5)=+2.5 so 1.5-(-2.5)=1.5+2.5

    yes -4 doesn't makes sense distance is only positive or zero
