Answer:

  (D) is the best explanation

Step-by-step explanation:

The total number of students is 158 + 139 = 297. This number can be rewritten as ...

  297 = 37 × 8 + 1

That is, if there were 37 chaperones, 1 student would remain without a chaperone. That means the number of chaperones must be increased by 1 to 38. This is best explained by choice D.

Brenda had bowling scores of 92, 110, 85, 78, and 96. She completed the steps below to determine the score she needs in her next
Yakvenalex [24]

Answer:

<u>Hence final answer is B: Step 2.</u>

Step-by-step explanation:

Step 1: Find the total points needed to score in six games: 96x6=576

Justification:

Product of 96 and 6 is 576 which is same number found by Brenda. So step 1 is correct.


Step 2: Find the total points scored: 92+110+85+78=365

Justification:

Sum of total points scored by Brenda is 92+110+85+78= 461.

But she got different value 365.

Hence step 2 is wrong.


<u>Hence final answer is B: Step 2.</u>

Fine the value of the x in the triangle shown below.
Sever21 [200]

Answer:

x=28

Step-by-step explanation:

The interior angles of a triangle must add to 180 degrees

Therefore,

79+73+x=180

Combine like terms by adding 79 and 73

152+x=180

To solve for x, get x by itself. Since 152 is being added to x, subtract 152 from both sides. This will cancel the 152, and leave x by itself.

152-152+x=180-152

x=28

So, x is equal to 28 degrees
