The sum of two numbers is -10.5.
grandymaker [24]

Answer:

-5 and -5.5;

-12.5 and 2

Step-by-step explanation:

Two negative addends, can be added together to give -10.5.

For example:

(-5) + (-5.5) = -5 - 5.5 = -10.5

Also, it is possible for one of the addends to be negative while the other is positive, and their sum will give us -10.5.

For example:

The sum of -12.5 and 2 will give us -10.5.

We are adding a positive and a negative number here. As usual, we will subtract the smaller number from the bigger number, while the result will carry the sign of the bigger number, which in this case is negative sign.

Thus:

(-12.5) + (2) = -10.5

If the original quantity is 10 and the new quantity is 11, what is the percent crease?
LenKa [72]

Answer:

10 %

Step-by-step explanation:

We first find change in the quantities

Then we write the change in quantity on original quantity and multiply by 100%

This implies that,

\frac{11 - 10}{10} \times 100\%

=\frac{1}{10}\times100\%

=10\%

Therefore the percentage increase is 10%
