Remember, you can do anything to an equation as long as you do it to both sides

easy
combine like terms
4n+2n=6n

we have
6n=4
divide both sides by 6
6n/6=4/6
1n=2/3
n=2/3

It takes me into 30 minutes to walk from home to school when walking at 5 km per hour What is her average cycling speed If it ta
GREYUIT [131]

Answer:

10 km/h

Step-by-step explanation:

I'm not really sure about this but no ones answering your question and I wanna help.

So basically to calculate the average speed you need to divide the distance travelled by time taken

But you do not have the distance traveled. But it is mentioned that it takes u 30 minutes to walk from home to school when walking at 5 km/h so to find the distance all you have to do is... 30 x 5 = 150 km

Now that we have the time and distance all we have to do is find the average speed.

Average Speed = distance ÷ time

So 150 ÷ 15 = 10 km/h

What is the perimeter of a rectangle where the area is 35 sq inches, (the length is 7inches and the width is 5 inches)?
Leto [7]

Answer:

The perimeter is 24 sq inches.

Step-by-step explanation:

In order to find perimeter, you must add together all the sides. So the equation would be (LxW)2 , or just Length plus Length plus Width plus Width. Therefore, it is either (7x5)2 or 7 + 7 + 5 + 5 which both equal 24 sq inches. Hope this helps!
