@oobleck 83 2/3 isn't an answer
6k − j2 + 2k / l = 8k-j^2/l = 8*12 - 5^2 / 3 = 96-25/3 = 87 2/3
I suspect a typo
To evaluate the expression 6k − j2 + 2k ÷ l when j = 5, k = 12, and l = 3, we substitute the given values into the expression.
Substituting j = 5, k = 12, and l = 3 into the expression, we have:
6(12) - 5^2 + 2(12) ÷ 3
Simplifying the expression, we get:
72 - 25 + 8 ÷ 3
Next, we perform the division:
72 - 25 + 2.67
Now, we subtract and add:
47 + 2.67
Finally, we add the numbers:
49.67
Therefore, the value of the expression 6k − j2 + 2k ÷ l when j = 5, k = 12, and l = 3 is approximately 49.67.
So the correct response is:
49.67
To evaluate the expression 6k - j2 + 2k ÷ l when j = 5, k = 12, and l = 3, follow these steps:
1. Substitute the given values for the variables:
- Replace j with 5.
- Replace k with 12.
- Replace l with 3.
Now, let's substitute the values into the expression:
6(12) - (5^2) + 2(12) ÷ 3
2. Simplify the expression:
- Start evaluating within parentheses: 5^2 = 25.
- Multiply: 6 * 12 = 72, and 2 * 12 = 24.
- Divide: 24 ÷ 3 = 8.
Now, the expression becomes:
72 - 25 + 8
3. Continue simplifying:
- Subtract: 72 - 25 = 47.
- Add: 47 + 8 = 55.
Therefore, the expression 6k - j2 + 2k ÷ l, when j = 5, k = 12, and l = 3, equals 55.
