Answer:

1999 moves are required.

Step-by-step explanation:

Given is - In solving a jigsaw puzzle, a move consists of joining two clusters, including clusters of just one piece.

This means exactly n-1 moves are required to solve a jigsaw puzzle with n pieces.

Here, n = 2000

So, moves will be = 2000-1=1999

Hence. 1999 moves are needed to solve the puzzle.

Solution: As always, try to find a way of looking at the problem that makes the solution simple. In this problem, regardless of the current state of the puzzle, a move consists of combining two clusters into a single cluster. Therefore every move reduces the number of clusters by 1. Since we begin with 2000 clusters (the single pieces) and end with 1 cluster, we need \[2000-1=\boxed{1999}\] moves to complete the puzzle.

Paha777 [63]

Answer:

Step-by-step explanation:

The ordered pair is located on the boundary line of the graph of the inequality, and because the sign is "less than or equal to", the values on the boundary line are also included in the solution set.

Looking at this logically, we also see that it certainly possible for half the seats to be occupied by adults and half by children.

storchak [24]

Answer:

Brian has 50 pieces of gum

Step-by-step explanation:

Jaden has three times as many

Therefore-

n x 30 = 150

We need to solve for n

You can do that by dividing 150 by 3

150/3 = 50

So Brian has 50 pieces
