morpeh [17]

Answer:

<em>Then you </em><em>multiply:</em>

<em>3x+(-18)-4x+(-7)</em>

<em>then you </em><em>combine like terms:</em>

<em>3x-4x= -1x </em>

<em>-18+(-7)= -25</em>

<em>simplified:</em>

<u><em>-1x-30</em></u>

-7-2x=7(x+8) <br><br> What is the answer for this expression
sertanlavr [38]

Answer:

x=-7

Step-by-step explanation:

1. Distribute the 7 into the parenthesis: -7-2x=7x+56

2. Combine like terms by doing the opposite operation to the numbers:  -7=9x+56 (added 2x to 7x)

3. Subtract 56 to each side of the equation: -63=9x

4. To isolate the variable "x," divide each side by 9: x=-7

If an angle is obtuse what type of angle is its supplement
Butoxors [25]
The supplement of an obtuse angle is an acute because the angle number for an obtuse angle is any number greater than 90 degrees. So an acute angle is less than 90 degrees. The "supplement" definition is "any number less than 180 degrees." 

Hope this helps,
