Use PEMDAS
figure out everything inside the parentheses first, you still have to do PEMDAS inside of the parentheses also.
I will attach an image of how I got the first answer -7,867, sorry if my handwriting is sorta sloppy
The answer to "Round 10.054 To 2 decimal places" is 10.05
You could get two different functions out of this:
<u>2x + 2y = 8</u>
1). <u> 'y' as a function of 'x'</u>
Subtract 2x from each side: 2y = -2x + 8
Divide each side by 2 : <em> y = -x + 4</em>
2). <u> 'x' as a function of 'y' :</u>
Subtract 2y from each side: 2x = -2y + 8
Divide each side by 2 : <em> x = -y + 4</em>
Those two functions look the same, but that's just because the original
equation given in the problem was so symmetrical. In general, they're
not the same function.
It is the first choice. All you have to do is isolate A from 2A so you would divide by 2 and get A=bh/2
Answer
Find out the what was the price of the stereo .
To prove
Let us assume that the price of the stereo be x .
As given
Consumer Math The sales tax in the town where Amanda lives is 7%.
7% is written in the decimal form

= 0.07
As given
Amanda paid $35 in sales tax on a new stereo .
Than the equation becomes
x × 0.07 = 35

solving the above
x = $ 500
Therefore the price of the stereo is $ 500 .
Hence proved
