Step-by-step explanation: To determine if each pair is a solution to the equation, substitute the x and y variables in the pairs for the corresponding variables in the equation. If the left and right sides are equal once you solve, you will know that the pair is a solution,
(9,1) 2(9)+7(1)=16 18+7=16 25=16 No
(8,0) 2(8)+7(0)=16 16+0=16 16=16 Yes
(0,0) 2(0)+7(0)=16 0+0=16 0=16 No
We know that there are 7 days in one week. We are trying to figure out how many days there are in 9 weeks. To do this, we need to multiply the number of weeks (9) by the number of days per week (7).
9 * 7 = 63
Therefore, there are 63 days in 9 weeks.
