Question

+ - : x 40_30=50_5 32_4=25_17 54_6=72_8 8_6=90_42 7_5=70_2 37_8=9_5

Answer 1

40-30=50:5
8*6=90-42
7*5=70:2
37+8=9*5
32:4=25-17
54:6=72:8

Answer 2

40-30=50:5 32:4=25-17 54:6=72:8

Answer 3

It seems like you've provided a series of equations where each equation follows a pattern involving different mathematical operations. The goal appears to be to fill in the blanks (represented by underscores) with appropriate numbers to make the equations true. Let's solve each equation one by one:

1. 40 - 30 = 50 + 5 Here, the left side is 10 (40 - 30) and the right side is 55 (50 + 5), which are not equal. So, this equation is not true.

2. 32 + 4 = 25 - 17 On the left side, 32 + 4 is 36, and on the right side, 25 - 17 is 8. These are not equal, so this equation is not true.

3. 54 - 6 = 72 / 8 On the left side, 54 - 6 is 48, and on the right side, 72 / 8 is 9. These are not equal, so this equation is not true.

4. 8 + 6 = 90 - 42 On the left side, 8 + 6 is 14, and on the right side, 90 - 42 is 48. These are not equal, so this equation is not true.

5. 7 + 5 = 70 / 2 On the left side, 7 + 5 is 12, and on the right side, 70 / 2 is 35. These are not equal, so this equation is not true.

6. 37 - 8 = 9 * 5 On the left side, 37 - 8 is 29, and on the right side, 9 * 5 is 45. These are not equal, so this equation is not true.

It appears that none of the provided equations are true given the standard mathematical operations (+, -, *, /). If there is a specific pattern or rule that you have in mind for these equations, please provide additional information so I can help you understand or solve them accordingly.
