Answer:
A rational number is a number which can be written as a ratio of two whole numbers (integers). For example 5 is arational number since 5 can be written as ratio of 5 : 1 . ... 2.5 is a rational number since it is a ratio of 5 : 2 . And 2.5 is not an interger
Answer:
No solution
Step-by-step explanation:
3x + 5 - x = 2(x-1)-4
2x + 5 = 2x - 2 - 4 Add the like terms. Distribute the 2.
2x = 2x - 6 - 5 Subtract 5, add like terms
2x = 2x - 11 Add like terms
0 ≠ -11 Subtract 2x to keep variables on one side
Since zero does not equal -11, there are no solutions
The room is a square, meaning all four sides are 20ft long.
Because we know all the side lengths, we can find the perimeter of the square by adding the side lengths together.
(20 + 20 + 20 + 20) = 80
Now that we know the perimeter, we have to match this number to the feet of crepe paper.
We can find this by dividing the total length needed by the length a single roll provides.
80 / 8 = 10
Therefore, we know that Katie will have to buy a minimum of 10 rolls if she wants to cover the entire perimeter of the room.
Hope this helps! :)
