Simplify 2/√5

1 answer:

4 0

The answer would be 2√5/5

As a rule, you cannot have any radical as a denominator. That's why you gotta multiply √5 with √5 which would be √25. The square root of this is 5, and now you have disposed of the radical! Hurray. However, keep in mind, that when you multiply √5, you also multiply it to the numerator. So, yeah, after this, you get the answer.

Hopefully, my explanation makes sense. :)

It is given in the question that

Steven is solving the equation

$3(8-2x)+40=34$

He begins with the following two steps.

$Step 1: 3(8)+3(-2x)+40=34 Step 2: 24-6x+40=34$

And we have to find , what will be the next step in solving the equation.

First we combine the like terms. And the like terms are 24 and 40. So we have to add 24 and 40. And that will be the next step.

So the correct option is the last option.

On a map, 1/4 inch between locations represents an actual distance of 2 miles between the locations. What is the actual distance

natulia [17]

Answer:

30 miles

Step-by-step explanation:

1/4 = 2

3 3/4 = x

15/4 = x

So, Cross multiply

=> 1/4 * x = 15/4 * 2

=> 1/4x = 15/4 * 4/2

=> 1/4x = 60/8

=> 1/4x = 7.5

=> 1/4x * 4 = 7.5 * 4

=> x = 30

So, 15/4 inches on the map equals 30 miles.
