To evaluate 5y - 3z + 6 when y = 10 and z = 4, we substitute these values into the expression:
5(10) - 3(4) + 6
= 50 - 12 + 6
= 56 - 12
= 44
Therefore, the value of the expression is 44.

To evaluate 6k - j^2 + 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
= 47 + 8
= 55
Therefore, the value of the expression is 55.
6(12) - 5^2 + 2(12) ÷ 3
= 72 - 25 + 24 ÷ 3
= 72 - 25 + 8
= 47 + 8
= 55
Therefore, the value of the expression is 55.

To find the total number of points scored for 24 correct and 11 incorrect answers, we substitute these values into the expression 15c - 10a:
15(24) - 10(11)
= 360 - 110
= 250
Therefore, the player scores a total of 250 points for 24 correct and 11 incorrect answers.
15(24) - 10(11)
= 360 - 110
= 250
Therefore, the player scores a total of 250 points for 24 correct and 11 incorrect answers.

To find the perimeter of the garden, we use the formula 2l + 2w, where l is the length and w is the width.
Given that the length of the garden is 28 feet and the width is 16 feet, we substitute these values into the formula:
2(28) + 2(16)
= 56 + 32
= 88
Therefore, the perimeter of the garden is 88 feet.
Given that the length of the garden is 28 feet and the width is 16 feet, we substitute these values into the formula:
2(28) + 2(16)
= 56 + 32
= 88
Therefore, the perimeter of the garden is 88 feet.

To find the total time of the soccer game with 12 minutes of stoppage time, we substitute m = 12 into the expression 90 + m:
90 + 12 = 102
Therefore, the game is 102 minutes long with 12 minutes of stoppage time.
90 + 12 = 102
Therefore, the game is 102 minutes long with 12 minutes of stoppage time.
