The absolute value is always non-negative!

So the absolute value of 57 is 57 itself, as it's non-negative (i.e. it's positive or 0).

Opposite value is the number with a different sign: an opposite value of a positive number is negative, so here it will be -57 .

The correct answer is C.

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=13\pi \end{cases}\implies 13\pi =2\pi r\implies \cfrac{13\pi }{2\pi }=r\implies \boxed{\cfrac{13}{2}=r} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \textit{area of a circle}\\\\ A=\pi r^2\qquad \qquad \implies A=\pi \left(\cfrac{13}{2} \right)^2\implies A=\pi \left( \cfrac{13^2}{2^2} \right)\implies A=\cfrac{169}{4}\pi$

Aubrey is saving up to buy a new jacket. She already has $85 and can save an additional $7 per week using money from her after s

guapka [62]

Hey there! I'm happy to help!

We'll call our weeks w and call our total savings s.

We have an initial $85 and then we add 7 every week. This means that we will be adding 7 for every week, so we will put this in our equation as 7w.

Therefore, our equation would be s=7w+85

Now, we plug in 8 for our w value to see how much money she will have after 8 weeks.

s=7(8)+85

s=56+85

s=141

Therefore, Aubrey will have saved $141 after 8 weeks.

I hope that this helps! Have a wonderful day! :D
