3x + 1 = 2x + 5
help .....
Answer:
x = 4
Step-by-step explanation:
Combine like terms.
3x- 2x = 1x
New Equation: 1x + 1 = 5
Subtract 1 from 5.
New Equation: 1x = 4
Divide 1 from both sides. 1x / 1 cancels out and 4 / 1 = 4.

Find 2.64 / 0.6 step by step
Answer: 4.6
Step-by-step explanation:
A swimming pool is treated periodically to control harmful bacteria growth.
The concentration of bacterial per cm³ after t days is given by
C(t)
[tex] = 30t^2 -240t + 500 [/tex]
in how many days after a treatment will be concentration be minimal ?
Answer:
The answer is 4
Step-by-step explanation:
[tex]c \: (t) = {30ft}^{2} = - 240t + 500[/tex]
For a quadratic function as given to find the minimum you need to write it in vertex or find the vertex (the vertex in a quadratic function is thr maximum or minimum).
Use the next formula to find the t coordinate of the vertex (the time in the minimum concentration of bateria):
[tex]c \: (t) = {at}^{2} + bt + c \\ \\ tm = - \frac{b}{2a} [/tex]
For the given function:
[tex]tm = - \frac{ - 240}{(2)30} = \frac{240}{60} = 4[/tex]
The minimum concentration of bacteria will be after 4 days.

Answer:
Primary Data Secondary Data
Reliability and Suitability
Primary data are more reliable and suitable for the enquiry because it is collected for a particular purpose. It is less reliable and less suitable as someone else has collected the data which may not perfectly match our purpose.
Answer:
(2) Time-consuming This method is time-consuming as investigator personally visits the various places and meet different people to collect information.
3) Secondary data is usually gathered from the published (printed) sources. A few major sources of published information are mentioned below: Published articles of local bodies and Central and State Governments. Statistical synopses, census records and other reports issued by different departments of the Government.
4) National Sample Survey Organisation (NSSO) is the largest and a very prominent agency of India working for the collection of data on various economic variables such as education,health,literacy rates, etc. ... Census of India is responsible for the collection of data related to different demographic characteristics.
5)The investigator must ensure that the data are suitable for the purpose of enquiry. 2. Inadequate Data: Adequacy of the data is to be judged in the light of the requirements of the survey as well as the geographical area covered by the available data.
6)The principles to be followed while drafting questionnaire are: 1) The questionnaire must not contain many questions, as greater the questions, lesser will be the possibility of reply from respondents. 2) The questions should be brief and clear. 3) The questions should be arranged in a logical order.
7) Reliable and Accurate: Results based on census method are accurate and highly reliable. This is because each and every item of the population is studied. Less Biased: Results based on census method are less biased. It is because of the absence of investigator's discretion regarding the selection of sample items.
8) It allows us to get near-accurate results in much lesser time. When you use proper methods, you are likely to achieve higher level of accuracy by using sampling than without using sampling in some cases due to reduction in monotony, data handling issues etc.
Step-by-step explanation:
this is the correct answer you want
please follow me ☺️.
1. Primary data is much more reliable than secondary data. This is because primary data gives up-to-date information about a topic and is collected by doing research, avoiding the use of secondary sources which may include false and not up-to-date information.
2. The most common methods of collecting primary data are interviews, field observations, self-administered surveys, and experiments.
The experimental method:
merits:
-the researcher can have control over variables
-gains insight into methods of instruction
-can be used to determine what's best for the population
demerits:
-sample may not be representative
-human response can be difficult to measure
-subject to human error
---------------
5. Some precautions that should be considered when using secondary data are:
Reliable agency:
-must ensure that the agency that has published the data should be reliable
Method of collecting data used:
-The investigator should also be aware of the method that was used in collecting the data
-Sampling method may be biased depending upon the mode of selection of samples.
-All these should be ascertained before making use of the secondary data.
Suitability for the purpose of an enquiry:
-The Investigator must ensure that the data are suitable for the purpose of the present enquiry.
-The suitability of the data is determined by investigating the nature, objectives, time of collection, etc. of the secondary data.
Adequacy and accuracy to avoid the impact of bias:
-It is necessary to use adequate data to avoid biases and prejudices leading to incorrect conclusions.

4p = 14.4
What is the value of p?
A. 3.6
B 3.8
C.10.4
D.57.6
Answer:
A. p = 3.6
Step-by-step explanation:
4p = 14.4
To get p by itself we would divide by 4 on each side so
(4p / 4) = (14.4 / 4)
p = (14.4 / 4)
p = 3.6

9514 1404 393
Answer:
32
Step-by-step explanation:
The first term is 5 and the common difference is 9-5=4, so the n-th term is ...
an = a1 +d(n -1)
an = 5 +4(n -1) = 4n +1
Then the term number for the term 129 is ...
129 = 4n +1 . . . . . put the given value in the formula
128 = 4n . . . . . . . subtract 1
32 = n . . . . . . . . . .divide by 4
The 32nd term is 129.

ANYONE KNOW HOW TO SOLVE THIS!!!! PLEASE HELP ME!!! IT IS SOLVING SYSTEM EQUATIONS BY SUBSTITUTING!!
x+8y=20
4x-y=14
Answer:
x=4
y=2
Step-by-step explanation:
x+8y=20
4x−y=14
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
x+8y=20,4x−y=14
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
x+8y=20
Subtract 8y from both sides of the equation.
x=−8y+20
Substitute −8y+20 for x in the other equation, 4x−y=14.
4(−8y+20)−y=14
Multiply 4 times −8y+20.
−32y+80−y=14
Add −32y to −y.
−33y+80=14
Subtract 80 from both sides of the equation.
−33y=−66
Divide both sides by −33.
y=2
Substitute 2 for y in x=−8y+20. Because the resulting equation contains only one variable, you can solve for x directly.
x=−8×2+20
Multiply −8 times 2.
x=−16+20
Add 20 to −16.
x=4
The system is now solved.
x=4,y=2

feet = 5/6 in a mile
Please give me a reasonable explanation, not just the answer. Thank you
One mile = 5,280 feet.
Understand?
I am assuming that you want to know what is 5/6 of a mile.
(5/6)(5,280) = 5(880) = 4,400 feet.
If by IN A MILE you mean division, then we do the following:
(5,280)/(5/6) = (5,280 • 6)/5 = 6,336.
Is either one or the other because your question is honestly not too clearly stated..

Write the equation, in standard form of the quadratic relation
Zeros of 5 and 6 and a y-intercept of 30
Answer:
[tex]f(x)=x^2-11x+30[/tex]
Step-by-step explanation:
The factored form of a quadratic is given by:
[tex]f(x)=a(x-p)(x-q)[/tex]
Where p and q are the zeros, and a is the leading coefficient.
The quadratic relation has zeros of 5 and 6, and it has a y-intercept of 30.
Since the zeros are 5 and 6, p and q are 5 and 6. Thus:
[tex]f(x)=a(x-5)(x-6)[/tex]
The y-intercept is 30. In other words, when x = 0, f(x) = 30:
[tex]30=a(0-5)(0-6)[/tex]
Solve for a:
[tex]30=a(-5)(-6)\Rightarrow 30=30a\Rightarrow a=1[/tex]
Therefore, our quadratic in factored form is:
[tex]f(x)=(x-5)(x-6)[/tex]
To find the standard form, expand:
[tex]\begin{aligned} f(x)&=(x-5)(x-6)\\&= (x-5)x+(x-5)(-6)\\&=(x^2-5x)+(-6x+30)\\&=x^2-11x+30\end{aligned}[/tex]

PLEASE EXPLAIN IT IS SUPER DUPER URGENT Explain how to find the area of a triangle if the height of the triangle is 24 ft and the base of the triangle is 8 ft. Please use complete sentences and mathematical words. Minimum of 5 sentences.
Answer:
You have to multiply 24 and 8, which will give you 192. For a triangle, you always must divide by two, and doing so on this equation will give you 96. Like everything involving area, or something with a measurement, you must use the proper measurement unit, in this case that would be feet. In all, the answer is 96 feet for the overall area of the triangle. The formula for this process is A=[tex]\frac{hb}{2}[/tex]
