Answer:
5 2/5
Step-by-step explanation:
First, determine how many times 5 can go into 27 evenly, there should be no decimals! Therefore, 5 can go into 27, 5 times. Next, we know that there are 2 left over. This leaves us with 5 and 2/5.
Hope this helps!! :)

8 x - 1/2 = -4 - middle line
-3/4 x 8 = - 6 - side line
-3/4 - - 1/2 = -1/4 - top line
-1/2 - 1/2 = -1 - vertical line
If n is rational, it means that

Therefore when we do n² we can write it as

Remember that the product of two integer numbers is also an integer, therefore we can guarantee that

Then we can confirm that n² is the quotient of two integers and the denominator is not zero, therefore, n² is always rational, it cannot be an irrational number
Answer:

Step-by-step explanation:
Given that radius of the circle = 10
Using π, we need to find about which equation expresses the ratio of the circumference of the circle to the circle's diameter.
diameter of the circle = 2(radius) = 2(10)=20
circumference of the circle = 2 π r = 2 π (10) = 20 π
then ratio of the circumference of the circle to the circle's diameter is given by:
.
Hence required equation is 
The length of the rectangle is 8cm longer than the width.
l=w+8
If the length of the original rectangle is increased by 6cm and the width is increased by 3cm the perimeter is 76cm.
p=76=((l+6)+(w+3))*2=(l+6+w+3)*2=(l+w+9)*2
to solve this substitute l=w+8 into the p= equation:
p=76=((w+8)+w+9)*2=
76=(2w+17)*2
76=4w+34
42=4w
10.5=w
l=w+8=10.5+8=18.5
