Answer:

17. d

18. a

19. b

20. c

Step-by-step explanation:

0.23 x 0.3 = 0.069

Finding the reciprocal of 1 and three fourths could be found by multiplying the whole number to th denominator then adding the numerator on the value. That would be 7/4, just reverse it = 4/7.

The third one is

7x + 3 = 13

7x = 13 - 3

7x = 10, divide both sides by 7

x = 10/7

Complement of 45 is just the same..
