Step-by-step explanation:

<h3>Given P( -12 , -7 ) and Q( -8 , -4)</h3>

Now the mid point of PQ

(x, y) = { (-12-8)/2 , (-7-4)/2}

= (-20/2 , -11/2)

= ( -10 , -11/2 )

Wewaii [24]

Answer:

<h3> The numbers are 20 and 28</h3>

Step-by-step explanation:

x - the other number (the smaller one)

x+8 - 8 more than the other number (the larger number)

$\dfrac{x+8}x=\dfrac75\\\\(x+8)\cdot5=x\cdot7\\\\5x+40=7x\\^{\quad-40\qquad-40}\\{}\quad5x = 7x-40\\^{\quad-7x\quad-7x}\\-2x=-40\\^{\div(-2)\quad\div(-2)}\\{}\ \ x=20\\\\x+8=28$
