Answer:

x = -1

Step-by-step explanation:

3(x - 6) - 8x = -2 + 5(2x + 1)

3x - 18 - 8x = -2 + 10x + 5

-5x - 18 = 10x + 3

-15x = 15

x = -1

Answer:

[tex]x=-\cfrac{7}{5}[/tex]

[tex]3(x-6)-8x \:\bold{Expand}[/tex]

[tex]-2+5\left(2x+1\right)\:\bold{Expand}[/tex]

Answer:

80 cookies

Step-by-step explanation:

25% of 64 is 16
16+64=80

Imani made total of 8 cookies.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Imani was assigned to make 64 cookies for the bake sale.

let she made x cookies.

So, x = 64 + 25% of 64

x = 64 + 25/100 (64)

x = 64 + 64/4

x = 64 + 16

x = 80

Hence, the total cookies made is 80.

Answer:

Anything before 0 is negative. In this case we’re trying to “plot” - 1 2/3. It has to be between -2 and 0 on this plot.

Now lets imagine we have a center line between -2 and 0.
You’d get
-2, -1, 0

Now using that benchmark/ estimate, go towards the LEFT between -1 and -2. Now when reached about half way, go forward for a bit more and you should receive it.

Thats it!

Answer:

1. 0.8165 ; 2. 27.52 ; 3 = 3.8352 ; 4. 812.128 ; 5. 11.8513

Step-by-step explanation:

1. 3 - 2.1835 = 0.8165

2. 38.35 - (3.9 + 6.93) = 27.52

3. 8 - 4.1648 = 3.8352

4. 604 + 406.064 = 1010.064

604 - 406.064 = 197.936

1010.064 - 197.936 = 812.128

34,500

Step-by-step explanation:

34,528 rounds down rather than up because 528 is closer to 500 than 600 so it will round down to 34,500

Answer:

34,500

Step-by-step explanation:

34,528 = 34,500 because when you round the 5 in the hundred place the 2 isn't high enough to make the 5 round up so its 34,500.

5-10 round up 1-4 round down.

Answer:

  1 in = 500 km

Step-by-step explanation:

It is nice to choose a scale that leaves a little border, so one could probably make it ...

  10 in = 5000 km

  1 in = 500 km

__

If you'd rather have a "nice" ratio, you could use ...

  2.5 cm = 500 km   ⇒   1 : 20,000,000

_____

Additional comment

An inch is 2.54 cm, so using 2.5 cm for the same distance means the map is slightly smaller. It would end up about 9.8 inches wide, leaving a border of almost 0.6 inches on either side.

You might want a scale that makes it easy to draw using the tools you have. If your distances are in km, and you have an inch ruler, then the first choice might be better. If you have a centimeter ruler, then the second scale might work better for you.

The unitless scale is found by doing the division:

  [tex]\dfrac{2.5\times10^{-2}\text{ m}}{5.00\times10^5\text{ m}}=\dfrac{1}{2\times10^7}=\dfrac{1}{20,000,000}[/tex]

Answer:

A=25

Step-by-step explanation:

8-3=5

25/5=5

a=25

Answer:

A = 25

Step-by-step explanation:

To solve this equation, we have to find a number that can replace a that makes the equation true.

So, what number would fit?

Well, since a 5 is being divided by a, we have to find a number that 5 can  divided by 5 that gets 5.

This way, you can add 5 to 3 and get 8

Well, 5 x 5 = 25

So, 25 / 5 = 5

So, if we set a to 25, the equation is true

25 / 5 =5

5 + 3 = 8

Correct Answer: 25

Answer:

Hello there, your answer would be 270

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

We assume, that the number 3000 is 100% - because it's the output value of the task.

so that x is the value we are looking for.

If 3000 is 100%, so we can write it down as 3000=100%.

We know that x is 9% of the output value, so we can write it down as x=9%.

Now we have two simple equations:

3000=100%

x=9%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

3000/x=100%/9%

Now we just have to solve the simple equation, and we will get the solution we are looking for.

Solution for what is 9% of 3000

     - we multiply both sides of the equation by x and - we divide both sides of the equation by x

now we have:

9% of 3000=270

So, the answer is 270

Answer:

Step-by-step explanation:

Common ratio = 20/4 = 100/20 = 500/100 = 5
