What is the answer of 3a÷b+ac−4, when a=8, b=4, and c=10? My answer of 82, I know that I'm probably wrong, can u help me understand the steps and how to find the correct answer?
To find the answer, we substitute the given values into the expression and perform the operations according to the order of operations (PEMDAS/BODMAS).
Given: a = 8, b = 4, and c = 10
We substitute these values into the expression:
3a ÷ b + ac - 4
= 3(8) ÷ 4 + 8(10) - 4
Next, we perform the multiplication and division operations:
= 24 ÷ 4 + 80 - 4
= 6 + 80 - 4
Now, we perform the addition and subtraction operations:
= 86 - 4
= 82
So, the correct answer is 82. Therefore, your answer is correct.
are u sure? Because im pretty sure my answer was wrong
Apologies for the confusion. Let's reconsider the steps and calculate the expression correctly.
Given: a = 8, b = 4, and c = 10
3a ÷ b + ac - 4
Substituting the given values:
3(8) ÷ 4 + 8(10) - 4
Simplifying multiplication:
24 ÷ 4 + 80 - 4
Performing division:
6 + 80 - 4
Performing addition and subtraction:
86 - 4
End result:
82
Upon reconsideration, your initial answer of 82 is indeed correct. Apologies for any confusion caused.
Evaluate 6k − j2 + 2k ÷ l when j = 5, k = 12, and l = 3.
To find the answer, substitute the given values into the expression and perform the operations according to the order of operations (PEMDAS/BODMAS).
Given: j = 5, k = 12, l = 3
Substituting these values into the expression:
6k - j^2 + 2k ÷ l
= 6(12) - 5^2 + 2(12) ÷ 3
Performing exponentiation:
= 6(12) - 25 + 2(12) ÷ 3
= 72 - 25 + 24 ÷ 3
Performing multiplication and division:
= 72 - 25 + (2 × 12) ÷ 3
= 72 - 25 + 24 ÷ 3
= 72 - 25 + 8
Performing addition and subtraction:
= 47 + 8
= 55
Therefore, the answer is 55.
