Question

The number line shows the distance in meters of two jellyfish, A and B, from a predator located at point X:

A horizontal number line extends from negative 3 to positive 3. The point A is at negative 1.5, the point 0 is labeled as X, and the point labeled B is at 0.5.

Write an expression using subtraction to find the distance between the two jellyfish. (5 points)

Show your work and solve for the distance using additive inverses. (5 points)

Answer 2

k Let me solve it first

Answer 3

-1.5-.5= -2 the additive inverse is the opposite, so 1.5+.5=2

Answer 4

thats all ?

Answer 5

you sure?

Answer 6

@anglina4196

Answer 7

is that the answer?

Answer 8

This is the expression -1.5-.5=-2

Answer 9

thats the answer rightt?

Answer 10

how would I explain it?

Answer 11

That the additive inverse are called opposites and lie on the other side of the number line from each other, so just do the opposite of the expression, which is adding both of them, instead of subtracting

Answer 12

Wait let me check for sure

Answer 13

ok

Answer 14

soo???

Answer 15

Use the distance formula

Answer 16

????

Answer 17

@anglina4196 wdym?

Answer 18

Yah just keep it that way 1.5+.5=2
