A girl is on a train that is headed East at 100 miles per hour. The girl is walking at 5 miles per hour

nata0808 [166]

Answer: The speed is 105 miles/ hr and the direction of the train would be East if the girl is the frame of reference.

Step-by-step explanation:

Since we have given that

Speed of train = 100 miles per hour

Speed of girl = 5 miles per hour

Since the girl is moving towards the back of train.

So,it means train and girl are moving in opposite direction.

So, Relative speed would be

$100+5=105\ miles/hr$

Hence, the speed is 105 miles/ hr and the direction of the train would be East if the girl is the frame of reference.

Which expression is equivalent to the following complex fraction?

jeka57 [31]

$\dfrac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}=\dfrac{\frac{y}{xy}-\frac{x}{xy}}{\frac{y}{xy}+\frac{x}{xy}}=\dfrac{\frac{y-x}{xy}}{\frac{y+x}{xy}}=\dfrac{(y-x)xy}{(y+x)xy}=\dfrac{y-x}{y+x}$

What are the solutions to the quadratic equation (5y + 6)2 = 24?

lana [24]

To solve for y, apply the distributive property:
$10y + 12 = 24$
Then, subtract 12 from both sides and you will get:
$10y = 12 \\$
Then solve for y, by dividing both sides by 10.

Your final answer will be y=1.2
