Answer:

x = 63

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable. (Also sorry I'm answering all these questions these are just some of my favorite math problems lol.)

You are attempting to estimate the number of protester marching through the city
Alenkinab [10]

9514 1404 393

Answer:

  1000

Step-by-step explanation:

If the number of protesters per minute remains a constant, then you could write the proportion ...

  p/12 = 177/2.1

Multiplying by 12 gives ...

  p = 12(177/2.1) ≈ 1011.4

Here, minutes are given to 2 significant figures, and the initial count is given to 3 significant figures. The best you can hope for is that your estimate is good to 3 significant figures:

 1010 protesters

It is probably sufficient to report the number to 2 significant figures*:

  1000 protesters

_____

* Unfortunately, with a number like 1000, the only way you can tell it has 2 significant figures is to report it as 1.0×10³ or 10. hundreds. The trailing zeros are usually not considered significant.

Find the slope and y-intercept of 3y - 4x = 39
Alexus [3.1K]
<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>

3y = 4x + 39

y = \frac{4x}{3} + \frac{39}{3}

When x is 0, y = 0(x) +  \frac{39}{3}, so the y intercept is \frac{39}{3}

<h3>Next, the slope is simply the number in front of the x, </h3>

So  \frac{4x}{3} can be rearranged to  \frac{4}{3}x, so the slope would be \frac{4}{3}.


<h2>Hope this helps!</h2>

V125BC [204]

Answer:

Step-by-step explanation:

Equation

3x + 9 + 2x = x - 2x - 3              

Solution

Combine all the like terms.

3x+2x+9 =  x - 2x - 3

5x + 9 = -x - 3                            Add x to both sides of the equation

5x+x +9 = -x+x -3                      Combine

6x + 9 = - 3                                Subtract 9 from both sides of the equation

6x+9-9 = - 3-9                           Combine

6x = -12                                      Divide both sides by 6

6x/6 = -12/6

x = - 2

Answer x = - 2
