PLEEEASE HELP ME, QUICK!!!! ITS WORTH 20 POINTS!!!
tell me if the statement below is sometimes, always, or never true. justify your reasoning, (the Expressions x - 3 + y -3 represent the same value.)
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.

Step-by-step explanation:
Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo se deben realizar los siguientes cálculos:
30/200 = 15/100 = 15%
45/200 = 22.5/100 = 22.5%
55/200 = 27.5/100 = 27.5%
38/200 = 19/100 = 19%
32/200 = 16/100 = 16%
Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Mei has 2 yellow teacups and 5 brown teacups Which ratio compares the number of brown teacups to the total number of teacups
Answer: 5: 7
Step-by-step explanation:
The total number for teacups: 2 yellow teacups + 5 brown teacups = 7 teacups
the ratio compares the number of brown teacups to the total number of teacups is :
5: 7
The ratio that compares the number of brown teacups to the total number of teacups is 5: 7
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We are given that Mei has 2 yellow teacups and 5 brown teacups.
The total number for teacups is;
2 yellow teacups + 5 brown teacups = 7 teacups
Therefore, the ratio compares the number of brown teacups to the total number of teacups can be;
5: 7

Find the simple interest and amount when principal = Rs. 6000, rate = 6% per annum and time = 4 years
Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get
[tex]I=\dfrac{6000\times 6\times 4}{100}[/tex]
[tex]I=60\times 6\times 4[/tex]
[tex]I=1440[/tex]
Now,
[tex]Amount=Principal+Interest[/tex]
[tex]Amount=6000+1440[/tex]
[tex]Amount=7440[/tex]
Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.

which table and graph represents the equation y=2x i give brainly wjo ever it correct
Answer:
graph a and table a=B
Step-by-step explanation:
This is because for table a, if you subsite the numbers of x it would give you the answer for y such as y=2x, and since x is 2 y is 4, which is shown on the graph. And since it does not have any add ons, if you make x 0 it would be 0 so it would also be proportional through the orgin. so graph A is also correct.
