Answer:

-4°C

Key:

( | | ) = these in between numbers is the absolute value. <em>EXAMPLE: </em>|-8| = 8

Step-by-step explanation:

If it was -9°C and it <em>INCREASED </em>by 5°C, you need to <em>ADD.</em>

-9°C + 5°C

<em>*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and  make it either positive or negative, depending on which absolute value is the greatest (|9|).*</em>

-9°C + 5°C <u><em>OR </em></u> |9| - |5|

|9°C| - |5°C| = |4°C|<em> </em>= -4°C

(because the greatest absolute value, |9|, is negative, the answer is too.)

Solve the following inequality<br> 9x−2&gt;43
MrRissso [65]

Answer: x > 5

Explanation: First we want to look at our variable and ask ourselves what's happening to it. Since 2 is being subtracted from 9x, we always undo addition and subtraction first so we add 2 to both sides.

That gives us 9x > 45.

Now we need to undo multiplication and division. Since 9 is being multiplied by <em>x</em>, to get <em>x</em> by itself, we need to divide by 9 on the left side of the inequality. If we divide by 9 on the left side, we must also divide by 9 on the right side.

This leaves us with <em>x > 5</em> which is the solution to this inequality.

If a triangle has angles measuring 15 degrees and 45 degrees what is the measure of the triangle's third angle?
enot [183]

Answer:

120 degrees

Step-by-step explanation:

Remember that the interior angles of a triangle always add up to 180 degrees. We know that two of the angles (45 and 15) add up to 60 degrees. Now we just have to subtract the 60 degrees we have from the 180 degree total in order to get the measure of the missing angle.

180 - 60 = 120

Therefore... the answer is 120 degrees
