Max was solving the equation below and isn’t sure if his answer is correct. Explain to Max how he can check

Answer 2

Answer:
Well, first of all, the bottom 2 lines are cut off of the bottom of Max's solution,
and his final answer doesn't even appear there.

Here . . . let me complete it for you:
Under the part printed on the page should be:

   19 = 19x

   x = 1

=========================================

Now that Max has an answer, he can check it by writing it into the
original equation wherever there's an 'x' there.

The original:    (3x-6) / 8 = (7x-1) / 6

With Max's answer written in: (3·1 - 6) / 8 = (7·1-1) / 6

Simplify the left side:    (3 - 6) / 8 = (7·1-1) / 6
-3/8 = (7·1-1) / 6

Simplify the right side: -3/8 = (7-1) / 6
-3/8 = 6 / 6
-3/8 = 1
This result is not a true statement,
so 'x' can't be ' 1 '.

We have to go back, look through Max's work, and find his mistake.
(Actually, Max won't learn anything that way ... MAX should be looking through
his work to find his mistake. But life is not always fair.)

The third line of Max's solution is 3 (3x + 6) = 4 (7x - 1)

Then he goes on to clear the
parentheses, and the next line is: 9x + 18 = 28x - 1

That's where his mistake is. The left side is correct,
but on the right side, Max distributed the '4' incorrectly.
Shame on Max.
This line should be    9x + 18 = 28x - 4 .

Answer:

8 38/45 inches

Step-by-step explanation:

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Let us represent:

Length of regular size chocolate bar = x

Length of king size chocolate bar = y

A regular size chocolate bar is 5 and 4/9 inches long.

x = 5 4/9 inches

If the king size bar is 3 and 2/5 inches longer,

Hence:

y = x + 3 2/5 inches

The length of the king size bar is calculated as:

5 4/9 inches + 3 2/5 inches

(5 + 3) + ( 4/9 + 2/5)

Lowest common denominator = 45

8 + (20 + 18/45)

8 38/45 inches

Final answer:

The king size chocolate bar is 8 and 26/45 inches long, which is calculated by adding the given lengths of the regular bar and the additional length of the king size bar.

Explanation:

The question asks about the length of a king size chocolate bar given the lengths of a regular size bar and the additional length of the king size bar. To find the length of the king size bar, we need to add the additional length to the length of the regular bar. The regular bar is 5 and 4/9 inches long and the king size bar is 3 and 2/5 inches longer. If we add these lengths together:

5 4/9 + 3 2/5 = 8 and 26/45 inches

So, the length of the king size bar is 8 and 26/45 inches.

This problem involves basic arithmetic with fractions, which is a common concept in Mathematics for Middle School students. Remember that when adding fractions, you need to have the same denominator.

The distribution 4 has the greatest spread because the value of the standard deviation is 3.2

What is the standard deviation?

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

As we know, the standard deviation will give idea about the spread of the data.

As we can see in the distribution 4

The standard deviation = 3.2

And 3.2 is the bigger than all other distribution.

Thus, the distribution 4 has the greatest spread because the value of the standard deviation is 3.2

The sample with the greatest standard deviation relative to the mean has the greatest spread. Since the means are all similar, we just look at the distribution with the highest standard deviation. This is Distribution 4, with a standard deviation of 3.2.
