Answer:
C choice.
Step-by-step explanation:
We can either solve the equation or substitute x = 4 to find the true equation.
Solve The Equations
1. 4x=20
Our solution would be x = 5 as we move 4 to divide 20.
2. x/2=8
Our solution would be x = 16 as we move 2 to multiply 8.
3. x+8=3x
Our solution would be x = 4 which is the answer. We basically move x to subtract 3x as we get 8 = 2x.
Then we move 2 to divide 8 as we get x = 4.
[tex]x + 8 = 3x \\ 8 = 3x - x \\ 8 = 2x \\ \frac{8}{2} = x \\ x = 4[/tex]
4.
[tex]x = \frac{x + 5}{2} \\ 2x = x + 5 \\ 2x - x = 5 \\ x = 5[/tex]
We simply multiply the whole equation by 2 to get rid of the denominator.

The value of x = -22
Step-by-step explanation:
Given the expression
[tex]-0.57x+0.27x=6.6[/tex]
Add similar elements: [tex]-0.57x+0.27x=-0.3x[/tex]
[tex]-0.3x=6.6[/tex]
Multiply both sides by 10
[tex]-0.3x\cdot \:10=6.6\cdot \:10[/tex]
Refine
[tex]-3x=66[/tex]
Divide both sides by -3
[tex]\frac{-3x}{-3}=\frac{66}{-3}[/tex]
[tex]x=-22[/tex]
Therefore, the value of x = -22

Answer:
(5, 3 2/3)
Step-by-step explanation:
The centroid coordinates are the average of the vertex coordinates.
(A+B+C)/3 = ((2, 3) +(8, 1) +(5, 7))/3 = (2+8+5, 3+1+7)/3 = (15, 11)/3
The centroid is (5, 3 2/3).

A hospital wants to survey religious participants in their city about what they seek from a hospital chaplain, so
they randomly select 5 religious meetings in the city and survey every participant in those meetings.
What type of sample is this?
Answers
Using sampling concepts, it is found that this is an example of cluster sampling.
Samples may be classified as:
Convenient: Drawn from a conveniently available pool. Random: All the options into a hat and drawn some of them. Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed. Stratified: Also divides the population into groups. However, only some elements of each group are surveyed.In this problem, each religious meeting is a group, and all participants are surveyed, hence, we have an example of cluster sampling.

What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both.
Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
There are three colors.
We can infer that there are 3 ornaments of each color because there are 6 ornaments for each of the other two colors.

Choose the polynomial that is described. A trinomial in one variable of degree 3.a. 4r2-9t+7b. 3r2+4t-9 c. 4r3 d. 4r3 -9t +7
Answers
Answer:
C. 4r³
Step-by-step explanation
A trinomial is an expression having three terms. A polynomial with degree 3 that which its leading variable has a power of 3. For example an example of such polynomial in one variable is expressed as 2x³+4x²-7. This equation has 3 terms and the leading variable has a power of 3 with only x as the variable
From the given options based on the explanation, the correct answer will be 4r³. This can also be written as a trinomial as 4r³+0r²+0r
The rest contains more than one variable.
There is no trinomial.
A trinomial is a polynomial with three nonzero terms
Here we have to find trinomial in one variable of degree 3 .
Since in given four options a , b , d have equations in two variables and c have only one term so there is no trinomial.

One-to-one if every y value has exactly one x value mapped onto itMany-to-one if there are y values that have more than one x value mapped onto them.We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function

The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x). What is the sale price if the cereal cost $3.00?
$2.20
$2.50
$2.40
$2.30
Answers
Step-by-step explanation:
y = x - 0.2x
y = 0.8x
When x = $3.00, y = (0.8)($3.00) = $2.40.
The sale price is $2.40.
Answer:
$2.40
Step-by-step explanation:
y = x - 20% of x
where x is $3.00
20% would be 1/5 of 3.00 = 3/5
3 - 3/5 = 15-3/5 = 12/5 = $2.40
A bucket holds 4 liters of water. If a ladle can scoop out 14 of a liter, how many scoops will it take to empty the bucket?
Answers
Step-by-step explanation:
the ladle should scoop out 56 scoops to empty the bucket because if one scoop equals 1/14, there are 14 scoops per liter, and 4 liters, so 4 times 14 equals 56
The ladle should scoop out 56 scoops to empty the bucket
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity
Given,
A bucket holds 4 liters of water.
If a ladle can scoop out 14 of a liter We need to find how many scoops will it take to empty the bucket
We know that one scoop equals 1/14 liters
1 scoop=1/14 litres
1 litre=14 scoops
As there are 4 litres
We have to multiply 14 with four to find the number of scoops to take to make the bucket empty.
14×4
56
Hence, the ladle should scoop out 56 scoops to empty the bucket
