To find the decreased percentage,here's what we can do:
\frac{originl \: value - new \: value}{originl \: value}  \times 100\%

In this case,the eqaution would be:
\frac{280 - 210}{280}  \times 100\% \\  =  \frac{70}{280}  \times 100\% \\  =  \frac{1}{4}  \times 100\% \\  = 25\%
Hope it helps!

|-4w+2|=14<br> the bars mean absolute value
Pie

Answer:

If you are looking for what w equals, the w would equal 3

Step-by-step explanation:

You would take the absolute value which is how far away a value is from zero.

So you would get 4w+2=14

Then you would bring the positive 2 to the other side making it negative

now we have 4w=14-2 which is the same as 4w=12

and then, you would divide 12 by 4 and then you would get 3

so

w=3
