Percent means parts ot of 100
10%=10/100=1/10
'of' means mutily
10% of what=14
1/10 times what=14
mutiply both sides by 10
what=140
the number is 140
The solution to this would be x=2, y=-2

I need a question, then I will help
Step-by-step explanation:
Answer:
So we know that all angles add up to 360. We first subtract it by 81
Now we have 279 as an answer. But since 2w + 81 cant be 360 because it doesn't add up because you have to spaces in between them. It adds up to 180 not 360
<h2><u>
From your question its 180</u></h2>
Remember yo can do anything to an equation as long as you do it to both sides
so
remember distributive property
a(b+c)=ab+ac
so first distribute
2(3x)+2(-9)=18x
6x-18=18x
minus 6x both sides
-18=12x
divide both sides by 12
-18/12=x
-9/6=x
-3/2=x
easier way is to first divide both sides by 2
x=-3/2
