Answer:

7x-2, -x-6y+16, 5x-3

Step-by-step explanation:

I'm guessing the three expressions are:

1. 3(x+2) + 4(x-2)

2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)

3. 2(4x+3) - 3(x+1)

... 1. 3(x+2) + 4(x-2)

= 3x + 6 + 4x - 8

= 7x - 2

... 2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)

= 2x + 2y - 3x - 3y - y - 8 + 24 - 4y

= -x - 6y + 16

... 3. 2(4x+3) - 3(x+1)

= 8x + 6 - 3x - 3

= 5x - 3

Answer:

Step-by-step explanation:

1) Let x represent the sale price.

normal price = $39.95. This week they are on sale for 25% off the regular price. The amount taken off is

25/100 × 39.95 = 9.9875

Sale price = 39.95 - 9.9875 = $29.9625

2) number of games played by the tigers is 11 + 4 = 15

Percentage of games won is

11/15 × 100 = 73.3%

number of games played by the cubs is 10 + 3 = 13

Percentage of games won is

10/13 × 100 = 76.9%

3) increase in stock price = 61.5 - 52.63 = $8.87

Percentage increase = 8.87/52.63 × 100 = 16.85%

4) if 28 percent of seven graders went
