Answer: The conclusion is valid

Step-by-step explanation:

Number of students surveyed = 50

Number of students who visited a science museum = 20

Number of students who haven't visited a science museum = 30

Percentage of student that have visited a Science museum:

= 20/50 × 100

= 40%

The conclusion is valid based on the calculation.

2(n - 1) + 4n = 2(3n - 1)
Sloan [31]
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n -2
6n - 2 = 6n - 2 (equal)
6n - 6n = 2 - 2
0 = 0

whatever value you put into the place of n, you'll get 0 = 0

Find x if L is between N and M, and NL = (6x - 5), LM = (2x + 3), and NM = (3x+13)?
anastassius [24]

Answer:

x = 3

Step-by-step explanation:

Here, we want to find the value of x

By mathematical convention;

NM = NL + LM

Now, substitute individual values

3x + 13 = (6x-5) + (2x + 3)

3x + 13 = 6x-5 + 2x + 3

3x + 13 = 8x -2

Collect like terms

8x -3x = 13 + 2

5x = 15

x = 15/5

x = 3

A statement can help you organize the numbers to answer a question about percents
Semenov [28]

Answer:

<u> $50</u> is <u>27.02%</u> of <u>$185</u>.

Step-by-step explanation:

Money spent on clothing = $50

Money spent on Groceries = $100

Money spent on Gas = $35

Total money spent = $185

Our question is to find the percentage of total money that is spent on clothing.

Percentage money on clothing = \frac{Money spent on clothing}{Total money} × 100

                                                   = \frac{50}{185} × 100

                                                   = 27.02% (approx)

Hence,<u> $50</u> is <u>27.02%</u> of <u>$185</u>.
