What value of q is a solution to this equation? 10q = 80 Choices: (A)q = 8 (B)q = 9

Identify operation: Identify the operation needed to solve for q. The equation is 10q = 80, which means we need to isolate q. To do this, we will divide both sides of the equation by 10.Divide by 10: Divide both sides of the equation by 10 to solve for q. We perform the operation 80 ÷ 10 to find the value of q. q = 80 / 10 q = 8Check solution: Check the solution by substituting the value of q back into the original equation. Substitute q = 8 into the equation 10q = 80. 10 * 8 = 80 80 = 80 This is true, so q = 8 is the correct solution.

q

is a solution to this equation?

\newline

10q = 80

\newline

Choices:

\newline

(A)

q = 8

\newline

(B)

q = 9

Identify operation: Identify the operation needed to solve for $q$ . The equation is $10q = 80$ , which means we need to isolate $q$ . To do this, we will divide both sides of the equation by $10$ .
Divide by $10$ : Divide both sides of the equation by $10$ to solve for $q$ . We perform the operation $80 \div 10$ to find the value of $q$ . $q = \frac{80}{10}$ $q = 8$
Check solution: Check the solution by substituting the value of $q$ back into the original equation. $\newline$ Substitute $q = 8$ into the equation $10q = 80$ . $\newline$ $10 \times 8 = 80$ $\newline$ $80 = 80$ $\newline$ This is true, so $q = 8$ is the correct solution.
