help me please (:
(n-2) + n + (n+2) = 39
3 n = 39
n = 13
so
12 , 13 , 14
3 n = 39
n = 13
so
12 , 13 , 14
L + 2 L = 12
3 L = 12
L = 4 heads of lettuce
2 L = 8 tomatoes
3 L = 12
L = 4 heads of lettuce
2 L = 8 tomatoes
(n-1), n , (n+1)
3(n-1) - 4 = 2 n
3 n - 3 - 4 = 2 n
n = 7
so
6 , 7 , 8
3(n-1) - 4 = 2 n
3 n - 3 - 4 = 2 n
n = 7
so
6 , 7 , 8
