klio [65]

All you have to look at is the word "dropped" and you know it's a subtraction problem. In this case, it would be 8 - 15.

8 - 15 = -7

It would be -7<span>°C at midnight. I hoped this helped! :)</span>

how do you determine if the answer to a problem is negative or positive in division multiplication addition and subtraction

erica [24]

In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25

in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1

in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.

5+ (-5) = 0
5- (-5) = 10

Pleae help thanks a bunch

zloy xaker [14]

Hello!

You use the Pythagorean theorem to solve this

$a^{2} + b^{2} = c^{2}$

Put in the values it tells you to

$a^{2} + 4.4^{2} = 5.5^{2}$

Square the numbers

$a^{2} + 19.36 = 30.25$

Subtract 19.36 from both sides

$a^{2} = 10.89$

Take the square root of both sides

a = 3.3

The answer is 3.3

Hope this helps!
