What rules should you follow when adding and subtracting? check all that apply. 1. the exponents in scientific notation should be added or subtracted. 2. the exponents need to be the same so the leading numbers can be added or subtracted. 3. the result has the same number of decimal places as the least precise number. 4. the result has the same number of significant figures as number with the fewest significant figures.

Anumber is multiplied by 7. then 29 is added to the product. this sum is then divided by 2. the answer is 46. what was the original number? student's solution - the answer was 46. if this was the result of dividing by 2, the number at this point was 92. if this was the result of adding 29, the number at this point was 63. if this was the result of multiplying by 7, the original number was 9. solve this problem using a similar strategy. a number is multiplied by 10. then 32 is added to the product. this sum is then divided by 4. the answer is 28. what was the original number?
