We are asked whether 8^2 - 4 divided by 2 + 2 = 65.  
                                       64 - 4     divided by 4 is
                                          60 div by 4 = 15.  No, 65 is not correct.

Let's try again, following Order of Operations rules:

Anything within parentheses is done first, followed by exponentiation.  After that it's mult. or div., and after that it's addn. or subtr.

8^2 - 4 divided by 2 + 2 = 65
Do 8^2 first; correct result is 64.  
"-4 div by 2" is -2; adding 2 results in zero.
Then we have 64 = 65 (which is false.
Are you positive that the original problem included a '65,' not a '64?'

Your grades on three exams are 80, 93, and 91. What grade do you need on the next exam to have an average of 90 on the four exam
Pani-rosa [81]

<u>Answer:</u>

96

<u>Step-by-step explanation:</u>

Let's assume that the marks needed in the next exam is x. Then if the average becomes 90,

\frac{80 + 93 + 91 + x}{4}= 90

Now we can simply solve for x:

⇒ \frac{264 + x}{4}= 90

⇒ 264 + x = 360            [Multiplying both sides by 4]

⇒ x = 360 - 264            [Subtracting 264 from both sides]

⇒ x = \bf96

Therefore, you need to score 96 in your next exam to have an average of 90 on the four exams.

Answer:

first one is 82% second is 214%

Step-by-step explanation:

Step 1: Divide 288 by 351 to get the number as a decimal. 288 / 351 = 0.82

Step 2: Multiply 0.82 by 100. 0.82 times 100 = 82

Step 1: Divide 212 by 99 to get the number as a decimal. 212 / 99 = 2.14

Step 2: Multiply 2.14 by 100. 2.14 times 100 = 214
