Full solution

Q. What value of qq is a solution to this equation?\newline10q=8010q = 80\newlineChoices:\newline(A)q=8q = 8\newline(B)q=9q = 9
  1. Identify operation: Identify the operation needed to solve for qq. The equation is 10q=8010q = 80, which means we need to isolate qq. To do this, we will divide both sides of the equation by 1010.
  2. Divide by 1010: Divide both sides of the equation by 1010 to solve for qq. We perform the operation 80÷1080 \div 10 to find the value of qq. q=8010q = \frac{80}{10} q=8q = 8
  3. Check solution: Check the solution by substituting the value of qq back into the original equation.\newlineSubstitute q=8q = 8 into the equation 10q=8010q = 80.\newline10×8=8010 \times 8 = 80\newline80=8080 = 80\newlineThis is true, so q=8q = 8 is the correct solution.
