2A) 8N = (64/8)N = 64*(N/8) = 64*(.25)
  8N = 16

2B) S:N:J = 5:3:1
  S - N = 5 - 3 = 2 "ratio units" = 16 games. Jay has 1 "ratio unit" of games.
  Jay has 8 games.

2C) The upper left box must be 6, so the boxes on the right must be 2, 3, 4 in some order. The top box cannot be 2 or 3 because those choices cause a number to be used twice. The top right box is 4, the middle right box is then 3, and the bottom box must be ...
  A = 2.

2D) 4 half-squares are unshaded for a total of 2 of the 9 squares. Then the 7 shaded squares are 14 cm², or 2 cm² per small square. The 9 small squares add to ...
  18 cm²

2E) The Nth triangular number is the sum of all positive integers N and below. That is, the 4th triangular number is 4 + 3 + 2 + 1 = 10. The 5th triangular number adds 5 to that sum, so is 15. The Nth triangular number is the number of handshakes there will be between N+1 people.
  If there are 15 handshakes, there are 6 people in the room.

(The Nth triangular number t(n) is given by t(n)=n(n+1)/2. This can give rise to a quadratic equation that you can solve to find the number of people.)

To complete this component you will need to insert parentheses in Expression 2 to change the order of operations so the expressi
Alika [10]

Given:

The expression is 5+4\times 2+6-2\times 2-1.

To find:

The position of parentheses inserted in the expression to get the value 19

Step-by-step explanation:

We have,

5+4\times 2+6-2\times 2-1

Now,

(5+4)\times 2+6-2\times 2-1=9\times 2+6-4-1

(5+4)\times 2+6-2\times 2-1=18+6-5

(5+4)\times 2+6-2\times 2-1=18+1

(5+4)\times 2+6-2\times 2-1=19

There are more ways to apply the parenthesis, but we do not get 19.

5+4*\left(2+6\right)-2*2-1=32\neq 19

5+4*2+\left(6-2\right)*2-1=20\neq 19

5+4*2+6-2*\left(2-1\right)=17\neq 19

And many more possibilities.

Therefore, the expression after inserting the parentheses is (5+4)\times 2+6-2\times 2-1.
