The equation 3x+4=5x-4 has the solution set {4}. explain why the equation (3x+4)+4=5x-4)+4 also has the solution set {4}
cestrela7 [59]
Notice that the terms in parentheses on both sides of the equation are added to 4.

(3x + 4) + 4 = (5x - 4) + 4


So we can set the equation as.

3x + 4 = 5x - 4


Subtract 3x on both sides of equation.

4 = 2x - 4


Add 4 on both sides of equation.

8 = 2x


Divide both sides of equation by 2.

4 = x


4 is the only value that satisfies the statement.

What is the difference between the mean and the median of the data set?
natka813 [3]

Answer:

Your answer is 0 (zero).

<u>Step</u><u> </u><u>by</u><u> </u><u>Step</u><u> </u><u>Explanations</u><u>:</u>

<u>For</u><u> </u><u>mean</u><u>:</u>

1. Add all the numbers; which is 90

2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15

3. Your mean is 15

For Median:

1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22

2. Find the middle number(s), which are 12 &18

3. Add; 12 + 18 = 30

4. Divide; 30/2 =15

5. Your Median is 15

So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0

You have 36 pages to read for homework. In 5 minutes you read 10 page if you countinue to read at the same rate how many times w
kykrilka [37]

Answer:

18 minutes

Step-by-step explanation:

5 mins = 10 pages

10 mins = 20 pages

15 mins = 30 pages

20 mins = 40 pages

Just keep adding 5 to the minutes and 10 to the pages. then if you divide 10 by 5 (10÷5) you get 2.

2 is the amount of pages you read in 1 minute.

so 1 minute = 2 pages

Since you only need to read 36 pages, you know that it would at least take you 15 mintes to read 30.

then you start adding 1 minute until you get to 36 pages.

15 minutes = 30 pages

16 minutes = 32 pages

17 minutes = 34 pages

18 minutes = 36 pages

Therefore, it should take 18 minutes to read all 36 pages.

(A shorter way of doing this would be doing 10÷5=2, then just dividing 36 by 2 (36÷2) and you would get 18 which would be the minutes it would take you to read all 36 pages if you read at 2 pages per minute.)
