Answer:
x=9
Step-by-step explanation:
First, distribute the negative sign, changing (2x+9) to -2x-9
next, distribute. 10x+−2x+−9=(−3)(15)+(−3)(−4x)
then, combine like the like terms (10x+−2x)+(−9)=12x−45
then you get 8x+−9=12x−45, and you will subtract 12x from both sides, resulting in −4x−9=−45. To get -4x by itself, add 9 to both sides
lastly, divide both sides by -4
x=9
Answer:
<h2> 157 surveyed adult </h2>
Step-by-step explanation:
IF 22% of 714 surveyed adult made a statement, the actual number of those that made the statement can be gotten by simply evaluating 22% of 714 as shown below;
= 22% of 714
= 22/100 * 714
= (22*714)/100
= 15708/100
= 157.08
≈ 157 surveyed adult
<em>This means that about 157 surveyed adults made the statement. </em>
Answer:
Step-by-step explanation:
we have to get y by itself here i think
so
x + 2y = 12
2y = -x + 12
y = -1/2 + 6
7x + 2y = 0
2y = -7x
y = -3.5x
hope this helps <3
is a valid argument
is not a valid argument
For the first argument:
From the definition of absolute value function
if 
That is every positive number is its own absolute value. Since
,
we can argue that
so the first argument is valid
For the second argument:
From the definition of absolute value function
This means that
or
no part of the definition allow for the option 
. So the second argument is not valid.
