To evaluate the expression 5y - 3z + 6 when y = 10 and z = 4, we substitute these values into the expression:

5(10) - 3(4) + 6 = 50 - 12 + 6 = 44.

Therefore, the value of the expression is 44.

To evaluate the expression 6k - j2 + 2k ÷ l when j = 5, k = 12, and l = 3, we substitute these values into the expression:

6(12) - (5^2) + 2(12) / 3 = 72 - 25 + 24 / 3 = 72 - 25 + 8 = 55.

Therefore, the value of the expression is 55.

To find the total points for 24 correct and 11 incorrect answers, we substitute c = 24 and a = 11 into the expression:

15(24) - 10(11) = 360 - 110 = 250.

Therefore, the total points scored for 24 correct and 11 incorrect answers is 250.

To find the perimeter of the rectangular garden, we substitute l = 28 and w = 16 into the expression 2l + 2w.

2(28) + 2(16) = 56 + 32 = 88.

Therefore, the perimeter of the garden is 88 feet.
