Answer:
12cm
Step-by-step explanation:
1. Define the variable:
x = length of the rectangle
2x = width of the rectangle
2. Set the equation:
x + 2x is half of the rectangle
2(x + 2x) is the perimeter
So,
2(x + 2x) = 36
2x + 4x = 36
6x = 36
x = 6
Since x is the length, multiply it by 2 to find the width.
2x = 12
The total of the sweater is $27.
Divide 18/1 by 2/3. You would get 27. Which means 1/3 of the sweater is $9.
And 2/3 would be $18.

Answer:
So the model should represent either 
or
(its equivalent and simplified form.
Step-by-step explanation:
1) Originally the question wants to represent this quotient as tiles.
So,
We can still simplify it, but since we're dealing with 100 x 100 squares let's keep it this way
2) So the model should represent either or (its equivalent and simplified form.
Answer:
r = 13, 3
Step-by-step explanation:
| r - 8| = 5
All solutions for r by breaking the absolute value into the positive and negative components
r = 13, 3
