16. 8*19 = 8 * (20 - 1) = 8*20 - 8*1
= 160 - 8
= 152
or if you want to get fancy
8 * 19 = (10-2)(20-1) = 200 - 10 - 40 + 2
= 200 - 50 + 2
= 152

18. 2(9+3) = 18 + 6 = 24
or
2(9+3) = 2(10 + 2) = 20 + 4 = 24
or
2(12) = 24
whatever :)

23. 1. 8*19 = 8*(11+8).

2. 2(9+3) = 2 * 12.

36. Using the distributive property, an expression equivalent to 48 + 30 is

1. 👍
2. 👎
37. 1. (8 x 20) - (8 x 1)
2. (2 x 9) + (2 x 3)
3. (7 x 50) - (7 x 2) = 350 - 14 = 336
4.(9 x 80) + (9 x 1) = 729

Now idk if these are exactly in order, but I got 100%.
