Problem: You asked whether the answer to Q5 is 70 but you did not provide the text of Q5. 1. State the question as I understand it. You asked if Q5 has answer 70, but I cannot see Q5 here so I must ask for the problem statement to confirm. 2. Identify the type of problem. Determine whether Q5 is an arithmetic computation, an equation to solve, a percentage, an average, a geometry problem, or something else. 3. Use the appropriate formula or method. For example, for a linear equation $ax+b=c$ the solution is $$x=\frac{c-b}{a}$$ Important rule: $a\neq0$. 4. For a quadratic equation use the quadratic formula. For $ax^2+bx+c=0$ the solutions are $$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$ Check the discriminant $b^2-4ac$ to see if roots are real. 5. Show intermediate work and checks. Always substitute numbers step by step, simplify each arithmetic operation, and re-evaluate the result to catch arithmetic mistakes. 6. Quick illustrative example. If Q5 were "Compute 7 times 10" then compute $7\times10=70$ and 70 would be correct for that specific question. 7. How I can verify for you. Paste the full text of Q5 or the relevant numbers and I will verify step by step, show intermediate work, and give the final answer. Final answer: I cannot confirm that Q5 equals 70 without seeing the question; please paste Q5 so I can check and, if needed, show all steps to reach the correct answer.
