9. 31 + 5 = 36
10. 16 - 4 = 12
12. 9
13. 44 + 34 = 78
14. 101 - 1 = 100
15. -539 ???
16. 15 ??
17. |-435| = 435
To answer this multiply 3×7=21 and add 21+10=31. so it is 31/10 divided by 2. for that you do this...( top pic)
Do you have multiple choice answers?
Answer:
2/(x-3) = 4. 4x-12 = 2. x=7/2. G) 7/(2x+5) = 2/3. 21 = 4x + 10. x = 21/4. H) 7/(x-9) = 5. 7 = 5x-45. x = 52/5
