1)

4x - 3 = 5

4x = 8

x = 2

Hence, answer is x = 2

2)

42 / 3 = 14

14 x 2 = 28

Fred is 28 years old

3)

2/3 = 8/12

1/4 of 4/12 = 1/12

1/12 of money = $250

original money = $250 x 12 = $3000

4)

(bc / a)

5)

5 miles = 20 minutes = 1/3 hour

total distance = 5 + 10 = 15 miles

Total time taken = (15 / 5) x (1/3) = 1 hour

6)

Number of tickets sold = (186 - 67) + 1 = 120 tickets

7)

24 - 9 - 8 = 7

7 houses has 6 or 7 rooms

8 - 4 = 4

4 houses have 8 rooms

Total number of houses with 6, 7 or 8 rooms = 7 + 4 = 11 houses

8)

1/3
