What value of n makes the equation?
8n - 5 = -2n + 5 true?
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!

In a box there are 3 red pens, 2 green pens, and 1 blue pen. What is the probability of picking a red pen, not replacing it, and then picking a blue pen
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

Brad and Stella volunteer to help at the party. Brad volunteers at the prize table and Stella
volunteers at the refreshment table. Both workstations allow volunteers a short break, but at
different intervals. The prize table allows volunteers a short break every 20 minutes, but the
refreshment table allows a short break only every 30 minutes. If the party is scheduled to start
at 2:00 pm and Brad and Stella both start working then, what is the first time that they will be
on break together? Show all work.
Answer:
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
please simplify equations
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

48 = 4x – 2 + 6x
Need help ASAP
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!

The sales tax rate in Virginia is 4.5%. This is 2.5% less than the sales tax rate in Rhode Island. What is Rhode Island’s sales tax rate?
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%

Use two colors of counters to show a way to make 5.color to show the counters . Write the numbers to show the pair that makes 5
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.

HELP DUE LIKE RIGHT NOW
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!
What is 23569 rounded to the nearest ten thousand and thousand?
I NEED HELP PLEASE !!!!!
Answer:
c= (f-d)/ab
Step-by-step explanation:
abc+d = fSubtract f from both sides so abc= f-dDivide by ab from both sides so c = (f-d)/abIf the last line in your solution is x = 0, how many solutions are there? A) One Solution B) Two Solutions C) No Solutions D) Infinitely many solutions
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.
Solve for x???????????
Answer:
[tex]x=3/2=1.5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]49=7^{2x-1}[/tex]
Note that 49 is the same as 7 squared. Thus:
[tex](7)^2=(7)^{2x-1}[/tex]
Since they now have the same base, the exponents must be equal to each other. So:
[tex]2=2x-1[/tex]
Add 1 to both sides:
[tex]3=2x[/tex]
Divide both sides by 2:
[tex]x=3/2=1.5[/tex]
