how does the order of operations affect a equation? i really need to know

Answer:

0.672 is rational because it is a terminating decimal.

Answer:

1/10

Step-by-step explanation:

First, find the probability of choosing the red pen:

There are 6 total pens and 3 are red, so the probability will be 3/6

This can be simplified to 1/2

Then, find the probability of choosing a blue pen after not replacing the red one:

There are 5 total pens now, since we did not replace the red one.

There is only 1 blue pen, so the probability is 1/5

Then, multiply these 2 probabilities together:

1/2(1/5)

= 1/10

So, the probability is 1/10

Answer:

x = 2 because 5 times 2 = 10 and 10 - 2 = 8

Step-by-step explanation:

Answer:

[tex]n=1[/tex]

Step-by-step explanation:

[tex]8n - 5 = -2n + 5[/tex]

First, add 5 to both sides.

[tex]8n-5+5=-2n+5+5\\[/tex]

[tex]8n=-2n+10[/tex]

Then, add 2n to both sides.

[tex]8n+2n=-2n+10+2n[/tex]

[tex]10n=10[/tex]

Finally, divide both sides by 10.

[tex]\frac{10n}{10}=\frac{10}{10}[/tex]

[tex]n=1[/tex].

Answer:

[tex]n=1[/tex]

Step-by-step explanation:

So we have the equation:

[tex]8n-5=-2n+5[/tex]

First, add 2n to both sides. The right side cancels:

[tex]10n-5=5[/tex]

Add 5 to both sides:

[tex]10n=10[/tex]

Now, divide both sides by 7:

[tex]n=1[/tex]

And we're done!

Answer:

7.0%

Step-by-step explanation:

If the sales tax in Virginia is 2.5% less than Rhode Island, then the tax rate in Rhode Island is 2.5% MORE than Virginia, so we add it to Virginia’s tax rate.

4.5% + 2.5% = 7.0%

Answer:

There is one solution.

Step-by-step explanation:

x equals only one number which is 0 so there is one solution if there was like 0 = 0 it would be infinite if it was two different numbers, it would be no solutions.

Answer:

1 and 4, 2 and 3, and 5 and 0.

Step-by-step explanation:

Counters are used by educators to teach children how to do calculations like addition, subtraction, multiplication and division. Using color counters help to visualise the result from the operands in a calculation.

To get the pairs of numbers that adds to 5.

- Use the first color counter to mark out the five ones on the sheet.

- then with the second color counter, subtract one from the five ones.

- repeat the first two steps and increment the subtracted value until it gets to five.

Answer:

[tex]7x(x+2y-3yz)[/tex]

Step-by-step explanation:

First we find the greatest common factor of the coefficients, 7, 14 and 21.

The greatest common factor is 7.

Factor 7 out and divide the terms by 7:

[tex]7x^2+14xy-21xyz=7(x^2+2xy-3xyz)[/tex]

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

Next, we find the greatest common factor of [tex]x^2,xy[/tex] and [tex]xyz[/tex].

The greatest common factor is x.

Factor x out and divide the terms by x:

[tex]7(x^2+2xy-3xyz)=7x(x+2y-3yz)[/tex]

Answer:

24 =w

Step-by-step explanation:

1000 ^8 = 10 ^w

Rewriting 1000 as 10 ^3

10^3 ^8 = 10 ^w

We know a^b^c = a ^(b*c)

10 ^24 = 10^w

24 =w

Step-by-step explanation:

200+40n=480

40n = 280

n = 7

Answer:

The correct answer is x = 17.

Step-by-step explanation:

If EF bisects DEG, this means that angles DEF and angles FEG are congruent, and they each make up half of angle DEG.

Therefore, we can set up the equation:

DEF + FEG = DEG

However, since we know that DEF and FEG represent the same value, we can change this equation into the following:

2(DEF) = DEG

Now, we can substitute in the expressions that we are given:

2(3x+1) = 5x + 19

To simplify, we should first use the distributive property on the left side of the equation.

6x + 2 = 5x + 19

Our next step is to subtract 5x from both sides of the equation.

x + 2 = 19

Finally, we can subtract 2 from both sides of the equation to get x by itself on the left side.

x = 17

Therefore, the value of x is 17.

Hope this helps!

Answer:

x= 5

Step-by-step explanation:

48 = 4x – 2 + 6x

Combine like terms

48 = 10x-2

Add 2 to each side

48+2 = 10x-2+2

50 = 10x

Divide by 10

50/10 = 10x/10

5 =x

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 5}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{48 = 4x - 2 + 6x}[/tex]

Collect like terms

[tex] \longrightarrow{ \sf{48 = 10x - 2}}[/tex]

Swap the sides of the equation

[tex] \longrightarrow{ \sf{10x - 2 = 48}}[/tex]

Move 2 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{10x = 48 + 2}}[/tex]

Add the numbers: 48 and 2

[tex] \longrightarrow {\sf{10x = 50 }}[/tex]

Divide both sides by 10

[tex] \longrightarrow{ \sf{ \frac{10x}{10} = \frac{50}{10}}} [/tex]

Calculate

[tex] \longrightarrow{ \sf{x = 5}}[/tex]

Hope I helped!

They will be able to have their break together in 60 minutes.

Step-by-step explanation:

You will have to find the least common multiple (LCM) between 20 and 30.

The prime factorization of 20 is: 2 x 2 x 5

The prime factorization of 30 is: 2 x 3 x 5

Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(20,20) = 60

Step-by-step explanation:

to find the area more easily, you can divide the figure.

make a small rectangle from the upper part (a 5×6 rectangle) then a square from the lower part (a 5×5 square).

now you have a small rectangle, a big rectangle and a square.

small rectangle: 5×6=30

big rectangle: 15×5=75

square:5×5=25

30+75+25=130
