Solve for x using the<br> distributive property.<br> 9(5 - x) = 81<br> x = [?]

Ilya [14]

Answer:

$\boxed {x = -4}$

Step-by-step explanation:

Solve for the value of $x$ :

$9(5 - x) = 81$

-Use <u>Distributive Property</u>:

$9(5 - x) = 81$

$45 - 9x = 81$

-Subtract $45$ to both sides:

$45 - 45 - 9x = 81 - 45$

$-9x = 36$

-Divide both sides by:

$\frac{-9x}{-9} = \frac{36}{-9}$

$\boxed {x = -4}$

So, the value of $x$ is $-4$ .

The temperature at 6:00 pm was 24°. At midnight the temperature 36° lower than 6:00pm . What was the temp at midnight?

horrorfan [7]

Answer:

-12°

Step-by-step explanation:

Man... I just did 36 minus 24, and since it says 36° lower I decided it was -12 degrees (24 - 36 is more accurate but I find it easier just to do it the other way)
