3(x-5) = 2(x-5)+x true or false?
Answer:
FALSE
Step-by-step explanation:
In order to solve this equation,
First, we must write it out
3(x - 5) = 2(x - 5) + x
Then, we must use the Distributive Property
3x - 15 = 2x - 10 + x
Next, we must Combine Like Terms
3x - 15 = 3x - 10
Finally, we can Subtract The Coefficients
-15 = -10
Because -15 does not equal to -10, this equation has no solution
IT IS FALSE

Answer:
74
Step-by-step explanation:
1. Showing your knowledge in the problem
Well, you know that a straight line is 180 degrees, right? And you know that the angles are 52 degrees and 54 degrees. So, your equation would be set up like this: 52 + 54 + ____ = 180
2. What is 52 + 54?
106
3. Subtract 180 - 106
74
Hope that helps!
Answer:
180 - 52 - 54 = 74
x = 180 - 74 = 106°

Which of the following is a non-rigid transformation?
Answer:
c
Step-by-step explanation:
Answer:
B: Dilation
Step-by-step explanation:
Translations, rotations, and reflections are all rigid transformations because the image isn't altered. This makes a dilation a non-rigid transformation because the image is getting larger or smaller.
The perimeter of a playing field for a certain sport is 174 ft. The field is a rectangle, and the length is 45 ft longer than the width Find the dimensions.
The width of the playing field is 20 ft.
(Type an integer or a decimal.)
Answer:
21 ft by 66 ft
Step-by-step explanation:
From the question,
P = 2(L+W)............... Equation 1
Where P = Perimeter of the playing Field, L = Length of the playing Field, W = width of the playing Field.
If the Length of the Field is 45 ft longer than the width,
L = 45+W............ Equation 2
Substitute Equation 2 into equation 1
P = 2(45+W+W)
P = 90+4W............. Equation 3
Given: P = 174 ft.
Substitute into equation 3
174 = 90+4W
4W = 174-90
4W = 84
W = 84/4
W = 21 ft.
Substituting the value of W into equation 2
L = 45+21
L = 66 ft.
Hence the dimensions of the playing field is 21 ft by 66 ft

Three postal workers can sort a stack of mail in 15 minutes, 15 minutes, and 30 minutes, respectively. Find how long it takes them to sort the mail if all three work together.
min
Answer: 10 minutes
Step-by-step explanation:
x·1/20 + x·1/25 + x·1/100 = 1
Multiply each term by 100 to clear the equation of all fractions
100x/20 + 100x/25 + 100x/100 = 100
5x + 4x + 1x = 100
10x = 100
x = 10
The answer is 10 minutes

[tex]1 3/12-2/3=[/tex]
Answer:
[tex]\frac{5}{12}[/tex]
Step-by-step explanation:
The given problem is a subtraction problem between fractions. The first step in a problem like this is to convert both fractions to a common denominator. In other words, multiply both the numerator and denominator of a fraction by the same value such that the denominator of one of the fractions is the same as the other fraction. The numerator of a fraction is the value over the fraction bar, whereas the denominator is the value under it. Multiplying any fraction by a number over itself is the same as multiplying it by one, thus, the equation will remain true, and be equivalent to the original expression.
[tex]\frac{13}{12}-\frac{2}{3}[/tex]
Convert to a common denominator,
[tex]\frac{13}{12}-(\frac{2}{3}*\frac{4}{4})[/tex]
[tex]\frac{13}{12}-\frac{8}{12}[/tex]
Now perform the subtraction, subtract one numerator from the other, remember, do no perfrom any more operations with the denominators,
[tex]\frac{5}{12}[/tex]

An IQ test is designed so that the mean is 100 and the standard deviation is 21 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 6 IQ points of the true mean. Assume that σ=21 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.
Answer:
The required sample size is 82. This number of people could be sampled in an afternoon, for example, at a commercial center in a city, which means that it is a reasonable sample size for a real world calculation.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Assume that σ=21 and determine the required sample size.
A sample size of n is needed.
n is found when M = 6. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]6 = 2.575\frac{21}{\sqrt{n}}[/tex]
[tex]6\sqrt{n} = 2.575*21[/tex]
Dividing both sides by 3
[tex]\sqrt{n}= 2.575*3.5[/tex]
[tex](\sqrt{n})^2 = (2.575*3.5)^2[/tex]
[tex]n = 81.2[/tex]
Rounding up:
The required sample size is 82. This number of people could be sampled in an afternoon, for example, at a commercial center in a city, which means that it is a reasonable sample size for a real world calculation.

Show work please it has to be done at 2:35
Step-by-step explanation:
1. -10b+b=-9
It is like you are doing this:
-10+1=-9
5. 5k+7k=12k
5+7=12
3. 1+5v+v= 1+6v
Like: 5+1
2.-x-3x=-4x
Like:-3-1=4 (both are negative numbers and you just add the second one)
4.-7n-7-8+10n=3n-15
You are doing this with n:
10-7=3 and this with numbers:
-7-8=-15 (both negative again)
6.a-2+1+4a= 5a-1
Like this: 4+1=5 and -2+1=-1
7. 8(x+10)= 8*x+8*10= 8x +80
8. 8(1+6p)= 8*1+8*6p= 8+48p
9.-5(-7+7n)= 35-35n ( when you * negative and positive numbers you get negative result and when you * negative and negative numbers you get positive result)
10.-(9m+7)= -9m-7 ( when you have - before () every number changes its sign).
Sorry for messy writing... Hope this helps.
