<h2>Answer:</h2>

Option: B is the correct answer.

                 B.   2 pounds.

<h2>Step-by-step explanation:</h2>

It is given that:

Juan’s bag of apples that he bought weighed 31/7 pounds.

Ari’s bag of oranges that she bought weighed 19/3 pounds.

Let Ari's bag be x times heavier than Juan's bag.

This means that:

x=\dfrac{19}{3}-\dfrac{31}{7}\\\\i.e.\\\\x=\dfrac{19\times 7-31\times 3}{21}\\\\i.e.\\\\x=\dfrac{133-93}{21}\\\\i.e.\\\\x=\dfrac{40}{21}\\\\i.e.\\\\x=1.904

which is approximately equal to 2 pounds.

The amount by which Ari's bag is heavier then the Juan's Bag is approx : 2 pounds

The formula of a midpoint of AB:

M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have:

G(b; 0); F(3b; 2b)

substitute:

M_{GF}\left(\dfrac{b+3b}{2};\ \dfrac{0+2b}{2}\right)\to M_{GF}(2b;\ b)

Answer: (2b, b)

Each game was $44.99, if she spent a total of 284.97 and we subtract the cost of the console 284.97 - 194.99 = 89.98, since the two games were equally priced we divide 89.98/2 and get $44.98

A ladder is placed against the side of a house. The top of the ladder is 12 feet above the ground. The base of the ladder is 5 f
Colt1911 [192]
This is the Pythagorean theorem where the 2 legs of a triangle squared add up to equal the squared hypotenuse (a^2 + b^2 = c^2)

The equation would be
12^2 + 5^2 = x^2

144 + 25 = 169

The square root of 169 = 13

Answer - 13 ft
