Question

Evaluate the following expression: 24 ÷ 3 + 7 ⋅ 2 – 15 ÷ 5 + 6 ⋅ 2 A. 21 B. –31 C. 30 D. 31

Answer 1

24/3 = 824/3 = 8

8 + 7 * 2-15 / 5 + 6 * 28 + 7 ∗ 2−15 / 5 + 6 ∗ 2

7 * 2 = 147 ∗ 2 = 14

8 + 14-15 / 5 + 6 * 28 + 14−15 / 5 + 6 ∗ 2

15/5 = 315/5 = 3

8 + 14-3 + 6 * 28 + 14−3 + 6 ∗ 2

6 * 2 = 126 ∗ 2 = 12

8 + 14-3 + 128 + 14−3 + 12

14 + 8 = 2214 + 8 = 22

22-3 = 1922−3 = 19

19 + 12 = 3119 + 12 = 31

SORRY IF FALSE

Answer 2

Hello! :)

Answer:

`\boxed{=31}`

*The answer should be have a POSITIVE sign!

Explanation:

PEMDAS

Lesson: Order of operations

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

From left/right.

First, you multiply/divide from left to right.

`24/3=8`

`8+7*2-15/5+6*2`

`7*2=14`

`8+14-15/5+6*2`

`15/5=3`

`8+14-3+6*2`

`6*2=12`

`8+14-3+12`

Then, you add/subtract from left to right.

`14+8=22`

`22-3=19`

`19+12=31`

Final answer is 31.

Hope this helps!

Have a nice day! :)
