When Joanne checked her work by substituting the value of the variable back into the equation, she got an answer of 12.34 = 12.33. Explain why Joanne could have gotten the answer correct even though she did not get a true statement when she checked her work. Make the writing short

Answer 1

Joanne might have rounded the value of the variable during her calculations, leading to a slight discrepancy in the final result. If the exact answer is very close to 12.34, minor rounding errors could explain why she got 12.34 instead of the true value of 12.33. This small difference often occurs in practical calculations where precision is limited. Thus, her method was likely correct, even if the final check resulted in an approximate rather than an exact equality.
