$\angle{FJG} + \angle{GJH} = \angle{FJH}$

$\Rightarrow (6x - 15) + (x + 8) = 168°$

$\Rightarrow 7x - 7 = 168$

and this gives us

$7x = 175°$ or $x = 25°.$

Answer: 60 pages left.

Step-by-step explanation:

Let the number of pages in the book be x.

As per given, we have

$\dfrac14x+20=\dfrac13x\\\\\Rightarrow\ \dfrac{1}{3}x-\dfrac14 x=20\\\\\Rightarrow\ \dfrac{4-3}{12}x=20\\\\\Rightarrow\ \dfrac1{12}x=20\\\\\Rightarrow x=20\times12\\\\\Rightarrow x=240$

$\dfrac34$ of total book = $\dfrac34\times 240=180$

Pages left = 240-180

= 60

Hence, 60 pages left.

Step-by-step explanation:

In order to find the amount Chris will spend, start with the equation and input 100 for every x that you see.

c=0.765x +0.06(.765x)

c=0.765(100) +0.06(.765[100])

c = 76.50 + 0.06*(76.50)

c = 76.50 + 4.59

c = 81.09
