Answer:

Step-by-step explanation:

The common difference of an arithmetic sequence is the slope of the equation that describes it. The slope formula is useful in this case:

m = (y2 -y1)/(x2 -x1)

m = (219 -213)/(4 -2) = 6/2 = 3

The common difference of the corresponding arithmetic sequence is 3.

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.

Equation with angle addition can someone please answer please help

PQ peependicular to PS

Thus angle QPS = 90⁰

$\angle QPR + \angle RPS = \angle QPS$

7x - 9 + 4x + 22 = 90⁰

11x = 77

x = 7

Thus angle QPR = 7(7) - 9 = 40⁰
