I am doing with Question Number 2

Let the two numbers be 'x' and 'y'.

According to the question, the product of two numbers is 14.

$x \times y=14$

So, xy=14 (Equation 1)

Now, one of the numbers is 3 ½ times the other.

So, $x = 3\frac{1}{2}\times y$

$x=\frac{7}{2}y$ (Equation 2)

Substituting the value of 'x' from equation 2 in equation 1, we get

$\frac{7}{2}y \times y = 14$

$\frac{7}{2}y^{2} = 14$

$y^{2} = 4$

So, y= 2 and -2

So, $x=\frac{14}{2}$ and $x=\frac{14}{-2}$

x=7 and -7

Numbers are 2,7 and -2,-7.

Sum of numbers 2 and 7 = 9

Sum of numbers -2 and -7 = -9.

BigorU [14]

Answer:

The correct option is:

100 + 0.8(x - 100) = 250

Step-by-step explanation:

We are given that:

We know that a department store gives 20 % off the portion of the bill that is over 100 dollars.

Total bill is 250 and x is the amount of money she would have spent without the promotion.

The cost to which the discount applies is 0.8 ( x - 100 ).

<em>Finally the equation we get is 100 + 0.8 (x - 100) = 250.</em>
