Answer:
[tex] \sf \: x = - 20[/tex]
Step-by-step explanation:
Given equation,
→ 3x + 5 = 2x - 15
Now the value of x will be,
→ 3x + 5 = 2x - 15
→ 3x + 5 - 2x = -15
→ 3x - 2x = -15 - 5
→ x = -(15 + 5)
→ [ x = -20 ]
Hence, the value of x is -20.
When finding the mean, what does the total number of values mean in a set?
Answer:
It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. To find the mean, add up all the values in the set. Then divide the sum by how many values there are. So if you have five values, add them all together, then divide the result by five

Using a standard deck of cards, a gamer drew one card and recorded its value. They continued this for a total of 100 draws. The table shows the frequency of each card drawn.
Card A 2 3 4 5 6 7 8 9 10 J Q K
Frequency 4 7 5 6 7 6 8 10 7 10 8 12 10
Based on the table, what is the experimental probability that the card selected was a J, Q, or K?
A: one half
B: one third
C: 3 over 10
D: 3 over 13
Answer: its c i just took the flvs test
Step-by-step explanation:
The experimental probability that the card selected was a J, Q, or K is 1/3.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that a gamer drew one card and recorded its value.
They continued this for a total of 100 draws.
Card A 2 3 4 5 6 7 8 9 10 J Q K
Frequency 4 7 5 6 7 6 8 10 7 10 8 12 10
The total number of cards drawn is 4+7+5+6+7+6+8+10+7+10+8+12+10 = 90.
The number of cards drawn that are either a J, Q, or K is 10+8+12 = 30.
Therefore, the experimental probability of drawing a J, Q, or K is:
30/90 = 1/3
Hence, the experimental probability that the card selected was a J, Q, or K is 1/3.

Answer:
the answer should be B
Step-by-step explanation:
using advanced methods of taking tests and doing multiple choice I've come to realization the answer is never A and if the answer is a then you are wrong. the teachers always think that you're going to guess C so the answer will never actually be C. the last answer is D and the teacher will never make the answer D because who actually uses D. therefore using this advanced process of elimination we have cut the terms that answer should be and most definitely will be totally 100% be B. Trust
The answer is : d (2,6,18,54,162)
the geometric sequence formula : a+ ar^1 +ar^2+ar^3+...........
where r= common ratio
the sequence is : 2,6,18,54,162
r = An/An-1 ( as per the formula)
r = 162/54 = 3
r = 54/18 = 3
lly common ratio =3
in the given options the only option d satisfies all the conditions of the geometric sequence
verification :
a= 2
ar^1 = 2*3 = 6
ar^2 = 2*9 =18
ar^3 = 2*27 = 54
ar^4 = 2*81 = 162
hence verified the sequence is 2,6,18,54,162

Answer: The train travels 50 miles per hour
Step-by-step explanation:
You already figured out the slope! The explanation is that the train travels 50 miles each hour.
The Slope Intercept form of the equation would be y=50x
If you substitute x with any number you can solve to see how much hours the train traveled.
So the train travels 50 miles per hour!
I hope this is what you needed help with!

whats the formula for simple interest?....HELP
The formula for calculating simple interest is:
Simple Interest = (Principal x Rate x Time) / 100
Where:
Principal = the initial amount of money (the "principal sum")
Rate = the interest rate (expressed as a decimal or percentage)
Time = the length of time the interest is applied (usually in years)
It's important to note that simple interest is a method where the interest is calculated only on the original principal sum, not on any accumulated interest.
The simple interest formula is
i = P*r*t
where,
i = interestP = deposit or starting amount or loan valuer = annual interest rate in decimal formt = number of years--------------------
An example:
You borrow $500 at a simple interest rate of 2% over 3 years
P = 500r = 0.02t = 3Use those values to compute the following:
i = P*r*t
i = 500*0.02*3
i = 30
The amount of interest only is $30; meaning the total amount to pay back is $500 + $30 = $530

0.3 is greater than 0.03
0.3 > 0.03
The 3 comes first after the decimal point in 0.3, and a 0 comes first after the decimal point in 0.03 so 0.3 is bigger.
Answer:
0.3 > 0.03
Step-by-step explanation:
I think you should watch videos on decimals to see how to do them.
You see 0.03 has two places after the decimal point while 0.3 has one place after the point. You can match them by adding a 0 to 0.3 so that it also has two places to get a clearer look.
Like this:
0.3 turns into 0.30 so now it has two places after the point like 0.03
so if there is ONLY a 0 BEFORE the point, dont think about it. so lets look at the numbers AFTER the point. We added an extra 0 after the 3 so its 30. but the other decimal is only 03, which we can look at it as just the number 3 because only 0 is in front of it and 0 equals nothing.
looking at the two numbers 30 and 3, which one is greater? 30.
Therefore, 0.3 > 0.03

what number is expressed in each of the models below? One flat represents 1 whole. One rod represents 1 tenth, and one unit represents 1 hundredth. Write the number on the line.
Answer:
The number expressed in the models below is 0.63 (six tenths and three hundredths)
Step-by-step explanation:
It is represented as follows:
One flat represents 1 whole, so there are 0 whole numbers
One rod represents 1 tenth, so there are 6 tenths (represented by 6 rods)
One unit represents 1 hundredth, so there are 3 hundredths (represented by 3 units)

find the greatest possible decimal with 2 decimal places that is equal to 7 when rounded to the nearest whole number.
Answer:
7.49
Step-by-step explanation:
When rounding, if it is below 4 you round down, but above 5 is rounded up. Also, you look to the decimal closest to the number you are rounding. So, the greatest possible number is 7.49.

Answer:
a=-2
b=3
Step-by-step explanation:
Solve the system of equations.
2a -5b = -19
3a + 5b = 9
Add the two equations together.
2a -5b = -19
3a + 5b = 9
------------------------
5a = -10
Divide by 5
5a/5 = -10/5
a = -2
Now we can find b
2a-5b = -19
2(-2) -5b = -19
-4 -5b = -19
Add 4 to each side
-5b = -15
Divide by -5
b = 3
a=-2
b=3
Given
2a-5b= -19 (equation1)
3a+5b = 9 (equation2)
now add both equation 1 and equation 2
2a-5b=-19
3a+5b= 9
------------------
5a = -10 (as +5b and -5b get canceled)
5a = -10
a = -2
(substitute in equation 2 or in equation 1)
3(-2)+ 5b= 9
-6 +5b =9
5b = 9+6
5b = 15
b= 3
therefore
a= -2
b= 3
verification:
2(-2)-5(3) = -19
-19 = -19
hence verified.

B. 6 and 1 are both like terms, so B is correct
C. A coefficient is defined as a number multiplied by the variable, C is correct.
D. There are two terms, not 3
E. 8 is being multiplied so it is a factor, E is correct
F. 3 has been proven to be correct so F is wrong.
