Answer:

Step-by-step explanation:

Given that stefano has a spreadsheet containing data about the total number of students participating in different clubs in his school.

For number of students in different clubs comparison pie chart would be the best.

Box plot will not serve comparison of all club. But pie chart giving about the details of all the clubs and size is easy to understand and visualize.

Thus pie chart is the best one for representing graphically the relative popularity of each club.

Answer:

(Choice C) C Infinitely many solutions.

Step-by-step explanation:

First of all, let us learn about solutions of linear equations in one variable.

The linear equations in one variable usually have one solution.

For example:

$2x =x+3$

When we solve this:

$2x-x=3\\\Rightarrow x=3$

One solution is $x = 3$

But there can be situations when there are

1. No solutions:

For example:

$x =x+9$

It means that value x is equal to value of x+9 which can never be true.

Truth is the term on Right Hand Side is always 9 greater than the value of Left Hand Side.

Such situations are called Contradictions.

Here, no solution exists.

2. Infinitely many solutions:

For example:

$x+2x+8=3x+8$

The Right hand Side is just the simplification of the LHS.

And LHS is always equal to RHS no matter what is the value of variable $x$ .

It means there are infinitely many solutions for this equation.

-----------------------------------------------------

Now, let us have a look at the given equation in the question:

$-4x-7+10x=-7+6x$

Taking LHS: $-4x-7+10x$

Taking the terms with $x$ on one side:

$-7+10x-4x\\\Rightarrow -7+6x$

which is equal to Right Hand Side.

Hence, as we discussed in case 2 above.

For every value of $x$ the equation holds true.

$\therefore$ There exists infinitely many solutions to the given equation.

Correct answer is:

(Choice C) C Infinitely many solutions

15-20 pleaseee!!!! I really. Red help

15. First Distribute
-6x-4 = 2X + 6
Add 6X on both sides
-4 = 8x+6
Subract 6 on both sides
8x=-10
Divide by 8 on both sides
X = -10/8 = -5/4
16. -13
17. Cross Multiplication
32 = 3X-3
Add 3 on both sides
35 = 3X
Divide by 3 on both sides
35/3 = X
18. Can't see the whole picture
19. Add 7 on both sides
6N = 42. Divide by 6
N = 7
20. 2x+6=-x+1. ---- I cross multiplied
2x+5=-x. ---- I subract 1 on both sides
-3x = 5. ----- Subract 2X
X=5/-3 ---- I divided it by -3
