This is a fraction equal to
180 Pages ÷ 90 Minutes

We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 90

180 Pages÷ 90=2 Pages 1 Minute
=2 Pages Minute

= 2 Pages per Minute

<h2>▪Answer: Option D!</h2>

<h3>Explanation:</h3>

Given:

y = x +7
$y = {x}^{2} + 2x + 7$

<h2>Solution :</h2>

Substitute y=x + 7 in the second equation!

$y = {x}^{2} + 2x + 7$

$\implies \: x + 7 = {x}^{2} + 2x + 7$

$\implies \: {x}^{2} + 2x + 7 - x - 7 = 0$

$\implies \: {x}^{2} + x = 0$

$\implies \: x(x + 1) = 0$

 $\implies \: x = 0 \: or \: x = - 1$ 

Now put x = 0 in equation 1,

y = x +7

=> y = 0+7

=> y = 7

Now put x=-1 in equation 1,

y = x+7

=> y = -1+7

=> y = 6

<h3>The solutions are :</h3>

(0,7) and
(-1, 6)
