Q:
I need help with the ones withe the little marks by them
Accepted Solution
A:
Answer:Representing the situation:9. n + 12n = 9118. n + 10n = 9920. 12n +3 = 13521. 8(n+7) = 10426. 2(n+43) = 9427. 60 + n = 132Solving the equation:9. n + 12n = 91 13n = 91 n = 91/13 n = 718. n + 10n = 99 11n = 99 n = 99/11 n = 920. 12n +3 = 135 12n = 132 n = 132/12 n = 1121. 8(n+7) = 104 8n + 56 = 104 8n = 48 n = 626. 2(n+43) = 94 2n + 86 = 94 2n = 8 n = 427. 60 + n = 132 n = 72
