1.075(5.25)x - 5.25(0.25)(x-3)
Vitek1552 [10]

For this case we must simplify the following expression:

1,075 (5.25) x-5.25 (0.25) (x-3) =

So, solving the first parentheses we have:

5.64375x-1.3125 (x-3) =

We have to:

- * + = -\\- * - = +\\5.64375x-1.3125x + 1.3125 (3) =\\5.64375x-1.3125x + 3.9375 =

We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:

4.33125x + 3.9375

Finally, the simplified expression is: 4.33125x + 3.9375

ANswer:

4.33125x + 3.9375

Simplify 8 - {x - (5 + x)}. 3 13 -2x + 3 -2x + 13
love history [14]
<span>Simplify 8 - {x - (5 + x)}:

Order of operations rules require that you perform work inside parentheses first.  Thus, do this first:   </span>x - (5 + x)         =>  x - 5 - x   =>   -5.  

Now we have the following:           8 - {-5}    =>   8+5   = 13 (answer)

Please note:   To avoid confusion, please separate answer choices, such as <span>3 13 -2x + 3 -2x + 13, by using commas or by putting each choice on its own new line:

</span><span>3
13
-2x + 13
I was and still am unsure of what you meant here.</span>

\frac{1}{R}  =  \frac{1}{8}  +  \frac{1}{12}  \\

\frac{1}{R}  =  \frac{1 \times 3}{8 \times 3}  +  \frac{1 \times 2}{12 \times 2}  \\

\frac{1}{R}  =  \frac{3}{24}  +  \frac{2}{24}  \\

\frac{1}{R}  =  \frac{3 + 2}{24}  \\

\frac{1}{R}  =  \frac{5}{24}  \\

Inverse both sides

\frac{R}{1}  =  \frac{24}{5}  \\

R =  \frac{24 \times 2}{5 \times 2}  \\

R =  \frac{48}{10}  \\

R = 4.8 \:  \: Ω
