Let
a--------> the first whole number
a+1-----> the second consecutive whole number

we know that
if  <span> 90 lies between
then 
[a+(a+1)]/2=90-------> 2a+1=180----> a=179/2-------> a=89.5
a=89.5
a+1=90.5
but 
89.5 and 90.5 are not whole numbers

therefore
</span><span>No solutions exist
</span><span>

Vaselesa [24]

I can give you as many sums as you want!

All of these sums are 15, just so you know.

0 + 15 = 15

1 + 14 = 15

2 + 13 = 15

3 + 12 = 15

4 + 11 = 15

5 + 10 = 15

6 + 9 = 15

7 + 8 = 15

8 + 7 = 15

9 + 6 = 15

10 + 5 = 15

11 + 4 = 15

12 + 3 = 15

13 + 2 = 15

14 + 1 = 15

15 + 0 = 15

Can a positive and negative number be equivalent<br> and plz explain you know it
Sunny_sXe [5.5K]

Answer:

Yes! See explanation below!

Step-by-step explanation:

If a positive and negative number is equivalent, then they are called additive opposites meaning they add up to 0, basically cancelling out.

Ex:

1+-1=0\\1000000+-1000000=0\\\frac{1234}{1234}+-\frac{1234}{1234}=0
