Which number can not be used to write related number sentences? explain. 5 7 9 14

1 answer:

4 0

The number 7 cannot be used to write related number sentences because it wouldn't fit into the equation & make it true.
9 + 5 = 14
5 + 9 = 14
14 - 5 = 9
14 - 9 =5
Nowhere in any of these equations can the #7 go in, & make these number sentences true.
Hope this helps & makes sense ! (:

-10/5+2(7-9)^2

Answer: -4

Reasoning: so first you need to subtract the 7 from the 9 to get -2. Then you square it to get 4 because a negative 2 times -2 is 4. Then you multiply the 4 by the 2 to get 8. You can simplify the -10/5 to -1/2 and multiply that by the 8 to get -8/2 which simplified out to -4.

I hope that helps.
