Two third of a number is greater than one third of the number by 5. The number is ________
Let's assume the number as x
→ ⅔rd of x =( ⅔)x
Now ⅔ of x is greater than ⅓ of 5 .
[tex] \sf{ \implies \: \dfrac{1}{3} \times 5 = \dfrac{5}{3} } [/tex]
[tex]\sf{ \implies \: \dfrac{2}{3} \times x > \dfrac{5}{3} } [/tex]
[tex]\sf{ \implies \: x > \dfrac{5}{3} \times \dfrac{3}{2} }[/tex]
[tex]\sf{ \implies \: x > \dfrac{5}{2} }[/tex]
So number will be greater than 5/2 .

Step-by-step explanation:
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Step-by-step explanation:
The question says find the number eight times of a certain two digit number exceeding the number 19.The tens digit than the units digit . So,you have to multiply eight to a two digit number exceeding 19 so you find a number exceeding 19 which would have to be able to to multiply by eight to exceed the number 19
find the number eight times of a two digit number higher than the number nineteen. The tens digit than the units digit .you have to multiply 8 to a 2 digit number exceeding nineteen so you find a number exceeding ninteen which would have to be able to to times by 8 to go higher than the number nineteen
The equations of three lines are given below. Line 1: 6x-4y=6 Line 2: -2y=3x+5 Line 3: y=-2/3x+7 For each pair of lines, determine whether they are parallel, perpendicular, or neither.
Answer:
Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)
Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's
Line 2 and Line 3: Neither -- different slopes
Step-by-step explanation:
Lines are parallel if they have the same slope but different y-intercept.
Lines are perpendicular if the slopes are negative reciprocals.

Write 0.192 and 0.042 as a fraction. Write 189/1000 and 3/1000 as a decimal.
Answer:
0.192 = 24/125
0.042 = 21/500
189/1000 = 0.189
3/1000 = 0.003
As fraction
0.192 =
[tex] \frac{192}{1000} = \frac{24}{125} [/tex]
0.042 =
[tex]\frac{42}{1000} = \frac{21}{500} [/tex]
As decimal
189/1000 = 0.189
3/1000 = 0.003
The Bradenton Post polled 1,356 adults in the city to determine whether they wet their toothbrush before they put toothpaste on it. Of the respondents, 54% said they wet it first. Suppose 68% of all adults actually wet their toothbrush first. What are the mean and standard deviation of the sampling distribution?
Answer:
deviation = -95.50147493 mean = 61
Step-by-step explanation:
54% wet there brushes first
suppose 68% wet there brushes what is the mean
mean: a mean is where you add both numbers together to get a total then divide by how many numbers you added for now we wont need the amount of people we just need the percentages for this
54 + 68 = 122
we added to numbers so well divide by 2
122 divided by 2 or 122/2 is equal to 61
61 is our mean
standard deviation : this is were you take the known average 1356 adults and subtract the mean
1356- 61 = 1295 then divide by 1356 and times by 100
if the number is positive then the mean is higher than expected but luckily its a negative so its -95.50147493

Simplify ) 3/4 of 8/6
Answer:
First of all, to calculate what a fraction of a fraction is, we multiply them:
[tex]\frac{3}{4}*\frac{8}{6}[/tex] = [tex]\frac{3*8}{4*6}[/tex] = [tex]\frac{24}{24}[/tex] = 1
So now we know that three quarters of 8/6 is equal to 1.
We could also simplify 8/6 dividing both numerator and denominator by the same number:
[tex]\frac{8}{6}=\frac{\frac{8}{2}}{\frac{6}{2}}=\frac{4}{3}[/tex]
And see that 3/4 of 4/3 is also equal to 1:
[tex]\frac{3}{4}*\frac{4}{3}=\frac{3*4}{4*3}=\frac{12}{12}[/tex] = 1
Answer: 1

Select all of the following that have the same value as 30,452.
A. (3 x 1,000) + (4 x 100) + (5 x 10) + (2 x 1)
O B. (3 x 104) + (4 x 10°) + (5 x 10?) + (2 x 10')
OC. 30.000 + 400 + 50 + 2
D. thirty thousand, four hundred fifty-two
E. (3 x 10') + (4 x 10-) + (5 x 10") + (2 10')
F. thirty-four thousand, fifty-two
Answer:
d
Step-by-step explanation:
You could just do process of elimination. So for the first one if you add them all up you would get 3,452 which is not correct, for the second one would not be correct since after you do 3 times 104 you can see it is wrong, for c it is also wrong since there is a 30 not a 30,000, for d it is correct since if you write it out is is 30,452, for E it is not correct just by looking at the problem, and for F it cannot be correct since it does not be the right answer
The correct answer is thirty thousand, four hundred fifty-two.
What is expanded form?The expanded form helps us to better understand a given number. Let us take an example of the number 875294831. It is difficult to understand this number. Here an expanded form helps us to understand each of the digits based on their place value. Let us take a simple number 324 and try to find its expanded form. 324 is written in expanded form as 300 + 20 + 4. It means there are three hundred, two tens, and 4 ones in this number.
Given number:
30452
The expanded form is
=3*10000+0*1000+4*100+5*10+2*1
So, there is no match for this.
If we write in words it can be written as thirty thousand, four hundred fifty-two.
Hence, the correct option id (D).

Answer:
50
Step-by-step explanation:
When n = 6, the length is 3 * 6 + 2 = 20 and the width is 6 - 1 = 5. We know that the perimeter of the rectangle is twice the sum of its length and width. The sum of the length and width is 20 + 5 = 25 and twice that is 25 * 2 = 50.
Answer:
50
Step-by-step explanation:
At the bottom we see n = 6, that's already solved for us so now we plug it into the equation.
3n+ 2 and n - 1, When a variable is next to a number, you multiply the number of the variable and the original number together, So in this case n = 6 and we have 3n + 2, 3n = 18 (3x6) and then 18 + 2 = 20. And since n = 6, N - 1 = 5 (6-1) So we add the first sum of 3n+2 = 20 + N - 1 = 5 which gives us 25. Now that we have our sum of width and length we multiply that by 2 in order find the perimeter. 25x2 = 50.

Step-by-step explanation:
The length of a rectangle is 3ft more than twice the width, and the area of the rectangle is 54ft^2. Find the dimensions of the rectangle.
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft
