Answer: 41. A) 0 42. B) 1/12 43. B) 16
Step-by-step explanation:
The pattern is: multiply the bottom row and subtract the top number.
Sample: 3 x 2 - 5 = 1
5 x 3 - 6 = 9
2 x 1 - 1 = 1
41) 7 x 13 - x = 91
91 - x = 91
x = 0
42) 1/2 x 1/2 - 1/6 = x
1/4 - 1/6 = x
3/12 - 2/12 = x
1/12 = x
Check the fractions. I had to guess what the denominators are because the image is blurry.
43) 8 x 3 - 8 - x
24 - 8 = x
16 = 0
