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?

Answer 1

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.

Answer 2

are u sure? Because im pretty sure my answer was wrong

Answer 3

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.

Answer 4

Evaluate 6k − j2 + 2k ÷ l when j = 5, k = 12, and l = 3.

Answer 5

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.
