1. Solution: Let the price of each math book be X yuan, and the price of each Chinese book be (X+0.44) yuan.

24X+30×(X+0.44)=83.4

24X+ 13.2+30X =83.4

54X =83.4- 13.2

54X =70.2

X =70.2÷54

X = 1.3

1.3+0.44 = 1.74 (yuan) a: ———————

2. Solution: Let A have x kilograms and B have (12-x) kilograms.

( 12-X)×96- 132X=354

1 152-96X- 132 x = 354

228X = 1 152-354

228X= 1 152-354

X=798÷228

X=3.5

12-3.5=8.5 (kg) A: ——————

3. Solution: Let sunny days have X days and rainy days have (3+X) days.

16X- 1 1(3+X)= 27

16X- 1 1X-33 = 27

5X-33 =27

5X=27+33

x = 60 \5

X= 12

12+3 = 15 (days)

15+ 12 = 27 (days) A: ——

4.20×5= 100 (point)

100-76=24 (point)

24(5+ 1)= 4 (road)

20-4= 16 (Dao) a: ———————————

5. Solution: Let A play X, and B play (14-X).

A is missing (10-X), and B is missing 10-( 14-X)(X-4).

4X-( 10-X)×2-( 14-X)×5-(X-4)×3 = 10

4X-(20-2X)-(70-5X)-(3X- 12)= 10

(4X-20+2X)-(70-5X-3X+ 12)= 10

6X-20- (82-8X) = 10

6X-20-82+8X = 10

14X = 10+ 102

X = 1 12÷ 14

X 8 14-8=6 (F)

A: ————

6 solution: let Xiao Zhang's speed be x and Xiao Wang's speed be x- 1.5.

4 hours, Xiao Zhang walks for 3.5 hours and Xiao Wang walks for 3 hours and 20 minutes.

* * * Take 12 * 3 = 36km.

3.5x+(3+ 1/3) (note: it means walking for 3 hours and 20 minutes) *(x- 1.5)=36.

X= 6 kilometers per hour

Xiao Wang is 6-1.5 = 4.5 km/h.
