Answer:

$\huge{ \fbox{ \sf{12x - 28}}}$

Step-by-step explanation:

$\star{ \sf{ \: \: 4(5x - 6) - 4(2x + 1)}}$

$\text{Step \: 1 \: : Distribute \: 4 \: through \: the \: parentheses}$

$\mapsto{ \sf{20x - 24 - 4(2x + 1)}}$

$\text{Step \: 2 \: : Distribute \: 4 \: through \: the \: parentheses}$

$\mapsto{ \sf{20x - 24 - 8x - 4}}$

$\text{Step \: 3 \: : Collect \: like \: terms}$

$\text{Like \: terms \: are \: those \: which \: have \: same \: base}$

$\mapsto{ \sf{20x - 8x - 24 - 4}}$

$\mapsto{ \sf{12x - 24 - 4}}$

$\text{Step \: 4 \: : Calculate}$

$\underline{ \sf{Remember!}} : \sf{The \: negative \: integers \: are \: always \: added \: but \: posses \: the \: negative \: ( - ) \: sign}$

$\mapsto{ \sf{12x - 28}}$

Hope I helped!

Best regards! :D

Answer:

Step-by-step explanation:

You can't ever let this go negative. At least not at the grade you are in.

It can be 0.

So the domain must start at x = 7

sqrt(5*7 - 35) = sqrt(0) = 0

x can have any value (including 7) between 7 and infinity. If you choose a number less than 7 (like 6) the square root will go negative and that's not to be done.

So the interval is

7 ≤ x < ∞

Monica spent 3/4 hours listening to tapes of Beethoven and Brahms. She spent 1/5 hours listening to Beethoven . How many hours w

ELEN [110]

Answer:

Monica spent 0.55 hours listening to Brahms.

Step-by-step explanation:

We are given the following in the question:

Amount of time spent listening to tapes of Beethoven and Brahms =

$=\dfrac{3}{4}$

Amount of time spent listening to Beethoven =

$=\dfrac{1}{5}$

Total time spent listening to Brahms =

Amount of time spent listening to tapes of Beethoven and Brahms - Amount of time spent listening to Beethoven

$=\dfrac{3}{4}-\dfrac{1}{5}\\\\=\dfrac{15-4}{20}\\\\=\dfrac{11}{20}\text{ Hours}\\\\=0.55\text{ Hours}$

Thus, Monica spent $\frac{11}{20}\text{ hours}$ listening to Brahms.
