Q1.The cost of $16.50 for the music was reduction of 12% on the original cost.

NNADVOKAT [17]

Q1) £16.50 x 1.12 = £18.48
Q2)

2+9+1= 12
3h 33m = 213m
213/12 = 17.75
2x17.75 = 35.5 (music)
9x17.75 = 159.75 (films)
1x17.75 = 17.75 (books)

So it’s 159.75 minutes for the films to download

-4/7 + 2/7x - 14x + 4/7

alexgriva [62]

Answer:

The solved given expression is

$\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}$

Step-by-step explanation:

Given expression is $\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}$

To solve the given expression :

$\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}$

$=\frac{-4+4+2x}{7}-14x$

$=\frac{0+2x}{7}-14x$

$=\frac{2x}{7}-14x$

$=\frac{2x-14x(7)}{7}$

$=\frac{2x-98x}{7}$

$=\frac{-96x}{7}$

Therefore $\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}$

Therefore the solved given expression is

$\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}$
