For the first rectangle, the answer is 4n+1.2.

Explanation:

The perimeter is all the side lengths added together. That means, for this rectangle, the perimeter would be n+n+0.6+n+n+0.6, which can be simplified to 4n+1.2.

For the second rectangle, the answer is 6n+0.2.

Explanation:

Again, the perimeter is all the side lengths added together. That means, for this rectangle, the perimeter would be n+0.1+2n+n+0.1+2n, which can be simplified to 6n+0.2.

t When you reverse the digitals in a certain number you increase its value by 27. Find the number if the sum fixes digits is 9.

TiliK225 [7]

The number=10x+y
we suggest this system of equations:
(10y+x)-(10x+y)=27
x+y=9 ⇒x=9-y

Can solve this system of equations by susbstitution method.
(10y+(9-y)-(10(9-y)+y)=27
10y+9-y-(90-10y+y)=27
10y-y+10y-y=27-9+90
18y=108
y=108/18
y=6

x=9-y
x=9-6
x=3

The number=10x+y=10(3)+6=36

Answer: the number is 36.

to check:
63-36=27
6+3=9
