-3 because below is less and 3 less than zero is -3
6 because sea level would be zero and 6 above is 6
-5 cause your losing 5 pounds which means its 5 less so -5
4 because say you have zero dollars then you find 4 you now have positive 4
By finding the common denominator which is 20 and then what you multiply on the bottom you multiply on the top ; that is one method for adding. :)
Answer
1. - x < -y
Step by step explanation
When we multiply, add and divide the value remains the same.
But when you change the sign, the inequality direction will be > in this case, otherwise that is not ture.
For instance,
2 < 3
-2 < -3 is not true.
Because -2 is greater than -3
Hope this will help you.
Thank you. :)
So 5k-7=-7
You need to do the opposite of addition,which is subtraction so...
5k-7=-7
+7
__
K=0
and to double check it,replace the (or variable) with our answer (0)...
so
5×0-7=-7
solve the problem...and
-7=-7√
