Please help ill give whoever answers the best the brainliest answer :)))
Answer:
Step-by-step explanation:
A rational number can be in the form of a whole/natural number, integers, fractions and recurring decimals
In this case, 5 is a whole number, integer (can be a fraction too) , and of course, is a rational number.
As of which options to choose, read the above sentence carefully :)
Answer:
Natural, Integer, Rational, Whole
Step-by-step explanation:
First, we should know the definition of the word choices.
1) Natural Numbers: We can also count it as 'counting numbers'. Natural numbers are numbers that are a whole excluding the number 0. Some examples are 1, 2, 3, 4, 5 ... and so on.
2) Irrationals: They are numbers that cannot be written in a fraction form. Some examples are [tex]\sqrt{2} , \sqrt{3} , \sqrt{4} , \pi ...[/tex] etc.
3) Integers: They are a whole number that can be a negative, positive, or even a zero. Natural numbers are included in integers. Examples are -2, -1, 0, 1, 2, and so on.
4) Rationals: They are numbers that can be expressed in a fraction form, so it is the opposite of 'irrationals'. Examples are -1/2, 1/2, 2/4, 2/1 ... etc.
5) Whole Numbers: They are numbers that aren't a fraction. It can only be a positive number and a zero, so some examples would be 0, 1, 2, 3, 4, 5 ... and so on.
With these in mind, we can now solve the question. The number 5 is a natural, integer, rational, and a whole number.
Answer two questions about Equations AAA and BBB:
\begin{aligned} A.&&5x&=3x \\\\ B.&&5&=3 \end{aligned}
A.
B.
5x
5
=3x
=3
1) How can we get Equation BBB from Equation AAA?
The answers to the question about the equations are as follows:
1) A. Only add to or remove from one side.
2) B. No
1) As can be seen, the equations' left sides vary, while their right sides remain the same.
We must eliminate the difference in order to make them equal.
Formula A: 5x -2 + x = x -4
Formula B. 5x + x = x- 4
Equation B is created by multiplying the left side of equation A by 2.
The available response in this instance is:
A. Only increase or decrease an amount from one side.
2) The answers to the equations will differ since they are not identical.
Answer option:
B. No
The question was incomplete. The complete question was as follows:
Give two answers about Equations A and B:
A. 5x-2+x = x-4
B. 5x+x = x-4
1) From Equation A, how do we derive Equation B?
A. Only increase or decrease an amount from one side.
B. Increase/decrease the same amount on both sides.
C. Use the distributive principle to rewrite one (or both) sides.
D. Rewrite one (or both) sides using similar wording.
2) Are the equations equal in the light of the initial response? Do they share the same solution, in other words?
(1) Yes (2) No

Charlotte is 195 years younger than Rachel. 2 years later, Rachel will be thrice as old as Charlotte. Find their ages after 2 years. (Estimate the age to the nearest whole number).
Charlotte is 96 years old and Rachel is 292 years old
How to determine their ages?Let c represent Charlotte's age and r represents Rachels's age
From the question, we have:
c = r - 195
2 years later, we have:
r + 2 = 3(c + 2)
Expand the equation
r + 2 = 3c + 6
Subtract 2 from both sides
r = 3c + 4
Substitute r = 3c + 4 in c = r - 195
c = 3c + 4 - 195
Evaluate the like terms
-2c = -191
Divide by -2
c = 95.5
Approximate
c = 96
Substitute c = 96 in r = 3c + 4
r = 3*96 + 4
Evaluate
r = 292
Hence, Charlotte is 96 years old and Rachel is 292 years old

The value of a in the exponential function is 4/5.
Given the exponential function is f(x)=a(3/2)ˣ.
An function may be a mathematical relation of the subsequent form: f(x)=aˣ. where x may be a variable, and a could be a constant called the exponential of the function.
When multiplying the any function by a constant, we may expand or shrink the function in the y-direction.
y=a(b)ˣ
If a>1 then the function will enlarge.
If a<1 then the function will shrink.
When a=4/5
Then 4/5<1 means the function would shrink.
When a=5/4
Then 5/4>1 means the function would enlarge.
When a=3/2

Hope this helps!
If not, I am sorry.
How do you solve this?
It looks like your equations are
7M - 2t = -30
5t - 12M = 115
Solving by substitution
Solve either equation for one variable. For example,
7M - 2t = -30 ⇒ t = (7M + 30)/2
Substitute this into the other equation and solve for M.
5 × (7M + 30)/2 - 12M = 115
5 (7M + 30) - 24M = 230
35M + 150 - 24M = 230
11M = 80
M = 80/11
Now solve for t.
t = (7 × (80/11) + 30)/2
t = (560/11 + 30)/2
t = (890/11)/2
t = 445/11
Solving by elimination
Multiply both equations by an appropriate factor to make the coefficients of one of the variables sum to zero. For example,
7M - 2t = -30 ⇒ -10t + 35M = -150 … (multiply by 5)
5t - 12M = 115 ⇒ 10t - 24M = 230 … (multiply by 2)
Now combining the equations eliminates the t terms, and
(-10t + 35M) + (10t - 24M) = -150 + 230
11M = 80
M = 80/11
It follows that
7 × (80/11) - 2t = -30
560/11 - 2t = -30
2t = 890/11
t = 445/11
One year, there were about 3,000 institutions of higher learning in the U.S. (including junior colleges and community colleges). As part of a continuing study of higher education, the Carnegie Commission took a simple random sample of 400 of these institutions. The average enrollment in the 400 sample schools was 3,700, and the SD was 6,500. The Commission estimates the average enrollment at all 3,000 institutions to be around 3,700; they put a give-or-take number of 325 on this estimate. There were about 600,000 faculty members at institutions of higher learning in the U.S. As part of its study, the Carnegie Commission took a simple random sample of 2,500 of these faculty persons. On the average, these 2,500 sample persons had published 1.7 research papers in the two years prior to the survey, and the SD was 2.3 papers. If possible, find an approximate 95%-confidence interval for the average number of research papers published by all 600,000 faculty members in the two years prior to the survey. If this isn't possible, explain why not.
Thus an approximate 95% confidence interval for the average enrollment of all 60,000 faculty members in the two years prior to the survey. which implies that the given statement is true.
According to the statement
Average sample =3700
SD sample =6500
Sample size =400

The boundaries of the 68% confidence interval are then 1 standard error from the estimated average:
EV average+1⋅SE average =3700+1⋅325=3700+325=4025
EV average−1⋅SE average =3700−1⋅325=3700−325=3375

The tax paid by Rebecca on each cupcake was $0.15 or 15 cents, in the buying of 15 cupcakes for $47.25, where the cost of each was $3 plus taxes.
The tax is the amount paid to the government for buying and selling of goods are services.
In the question, we are informed that Rebecca bought 15 cupcakes, where each cupcake cost $3 plus taxes and the total bill to Rebecca was $47.25.
It implies that the cost of 15 cupcakes along with their taxes = $47.25.
Therefore, the cost of 1 cupcake along with its taxes = $47.25/15 = $3.15.
The cost of 1 cupcake is given as $3 plus taxes.
The total cost of 1 cupcake was $3.15.
Thus, the tax on 1 cupcake = $3.15 - $3 = $0.15 = 15 cents.

Point X is the incenter of ΔABC.
Triangle A B C has point X as its incenter. Lines are drawn from the points of the triangle to point X. Lines are drawn from point X to the sides of the triangle to form right angles. Line segments X F, X G, and X E are formed.
If EX = 4z + 1, XF = 2z + 7, and mABC = 44°, find the following measures.
GX =
mABX = °
The length of GX is 13 and the value of ∠ABX is 22.
We know that the point at which the triangle's three interior angle bisectors converge is known as the incenter. It can be thought of as the intersection of the triangle's internal angle bisectors. Due to the junction point of the central axis being the center of the triangle's inscribed circle, this point will be equally spaced from each of the triangle's sides. The center of a triangle's inscribed circle, which is the biggest circle that can fit inside the triangle, is known as the incenter.
Given that EX = 4z + 1 and XF = 2z + 7.
Since X is the incentre of this triangle ΔABC, EX = XF = GX.
Now, 4z + 1 = 2z + 7
i.e. 4z - 2z = 7 - 1
i.e. 2z = 6
i.e. z = 6/2 = 3
Then GX = 2 * 3 + 7 = 6 + 7 = 13
Also given that ∠ABC = 44°.
Since X is the incentre of this triangle ΔABC, ∠ABX = ∠CBX
Let ∠ABX = ∠CBX = y
Now y + y = 44
i.e. 2y = 44
i.e y = 44/2 = 22
Then ∠ABX = 22°
Therefore, the length of GX is 13 and the value of ∠ABX is 22°.
