Teds minimum grade he needs on his third test is 65

Answer: $\frac{1}{8}$

Step-by-step explanation:

The part of sandwich Keisha took to the picnic= $\frac{1}{2}$ of whole sandwich

The part of sandwich ate by family= $\frac{3}{8}$ of whole sandwich.

The part of sandwich Keisha bring back home= $\frac{1}{2}-\frac{3}{8}$

$=\frac{4-3}{8}\\\\=\frac{1}{8}$ of the whole sandwich.

Hence, Keisha bring back $\frac{1}{8}$ part of whole sandwich.

Rewrite each of the following expressions without using absolute value: |x-5|+|x+5| if x<-5

Ivahew [28]

For $x < -5$ :

$x-5 < 0 \Rightarrow |x-5|=-(x-5)=-x+5\\x+5 < 0\Rightarrow |x+5|=-(x+5)=-x-5$

So

$|x-5|+|x+5|=-x+5-x-5=-2x$

Can someone help me out

Sophie [7]

Firstly, you want to multiply (f^4)^2. $\frac{2*f^8*f^2}{8f^{12}}$

Next, multiply everything on the numerator. $\frac{2f^{10}}{8f^{12}}$

Next, divide. $\frac{2f^{10}}{8f^{12}}=\frac{1}{4} f^{-2}$

Now remember that f^-2 = (1/f^2), so just convert the negative powered exponent to that, and your answer will be $\frac{1}{4f^2}$
