Question

The number line shows the distance in meters of two birds, A and B, from a worm 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 2.5.

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

Show your work and solve for the distance using additive inverses

Answer 7

we have the subsequent drawing:

Answer 8

the requested distance d, is given by the subsequent formula:
\[\Large d = B - A = ...?\]

Answer 9

Ok so i have to write the answer in the answe box bow do i write it because i cant write a numberline???

Answer 10

hint:
\[\Large d = B - A = 2.5 - \left( { - 2.5} \right) = ...?\]

Answer 11

0??

Answer 12

no, it is:
\[\Large 2.5 - \left( { - 2.5} \right) = 2.5 + 2.5 = ...?\]

Answer 13

since: - * - = +

Answer 14

5

Answer 15

that's right!

Answer 16

Ok so can you write out for me how im going to write the answer in the answer box and thank you

Answer 17

you have to write:
d=5

Answer 18

Write it in the answer box

Answer 19

5

Answer 20

Right d=5 ? And how did you get it

Answer 21

since I applied this formula:
d=B-A
where A= -2.5, and B=2.5

Answer 22

So thats going to be what i right and thats all?

Answer 23

yes! we can solve your exercise, using fraction, like below:
\[d = B - A = \frac{5}{2} - \left( { - \frac{5}{2}} \right) = \frac{5}{2} + \frac{5}{2} = \frac{{5 + 5}}{2} = \frac{{10}}{2} = 5\]
