The given expression '5 × (2 + 4) = 6' can solve the problem (C).
What are expressions?You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression. Since 6 + 6 equals 12, the variable x in the example above is equal to 6. If we are aware of the values of our variables, we can substitute those values for the original variables before evaluating the expression.So, 5 × (2 + 4) = 6:
(A) To solve the situation (A), the expression will be:
5(2+4+6)(B) To solve situation (B), the expression will be:
[5(2 + 4)]/6(C) To solve the situation (C), the expression will be:
5 × (2 + 4) = 6Therefore, the given expression '5 × (2 + 4) = 6' can solve the problem (C).

in a sale , normal prices are reduced by 17%. the normal price of a washing machine is reduced by £42.50. work out the sales price of the washing machine
The sales price of washing machine is 250.
What is sales price?The price at which something sells or is offered for sale after having its price lowered is known as sales price.
A sale price is the reduced cost at which goods or services are offered for sale. Typically, this price is provided for a brief period of time in an effort to boost sales during a slow period or get rid of extra inventory.
The promotional price is indicated as a percentage off of the standard list price.
Let x be the sales price of washing machine, then as per given
17% of x = 42.5

for a population with a standard deviation of σ = 6, what is the z-score corresponding to a score that is 12 points above the mean?
The z-score corresponding to a score that is 12 points above the mean is 2.
The z-score is a numerical measurement used in statistics to determine the sample data value's relationship to the mean of a group of values, measured in terms of standard deviation from the mean. It is measured as the difference of the sample data value and the sample mean over the standard deviation, such that
z-score = (x – μ) / σ
where x = sample data value
μ = mean
σ = standard deviation
If the sample score is 12 points above the mean, then (x – μ) = 12.
(x – μ) = 12
σ = 6
Substitute the values to the z-score formula.
z-score = (x – μ) / σ

A farmer has 80 animals on his farm.The animals consist of cows and chickens .Given there are 216 legs altogether among the animals, how many cows are there?
The farmer has 28 cows from a total of 80 animals in the farm.
How many cows and chickens does the farmer have in the farm?
Each chicken has two legs and each cow has four legs. The farmer has a total of 216 legs among all the animals, which are 80. Then, we can represent the situation with the following system of linear equations:
x + y = 80
4 · x + 2 · y = 216
Where:
x - The number of cows.y - The number of chickens.The system can be solved easily by some algebraic handling:
x = 80 - y
4 · (80 - y) + 2 · y = 216
320 - 4 · y + 2 · y = 216
320 - 2 · y = 216
2 · y = 320 - 216
2 · y = 104
y = 52
x = 80 - 52
x = 28
The farmer has 28 cows.

Roaring Zoo has 68 different species of birds. Because of cold weather, only 24 species stayed at the zoo, while the others were transported to the barn until warmer weather returned.
Which equation shows how many species of birds were transported?
b + 68 = 24
b − 68 = 24
b + 24 = 68
b − 24 = 68
Answer: b + 24 = 68
Step-by-step explanation:
we are told the zoo has 68 different species of birds so the equation will be = 28. The answers showing = 24 are already wrong.
transported means they are taken away, so we have to subtract 24 (animals that stayed in the zoo) to find b which are the remaining species moved to the barn.
b + 24 = 68
- 24 -24
b = 44 (transported to the barn)
24 ( stayed in the zoo)
68 ( total number of species of birds)
The correct expression to show the species of transported birds will be;
⇒ b + 24 = 68
Where, b is the number of transported birds.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Total number of birds in Roaring Zoo = 68
Number of stayed birds in Zoo = 24
Let number of transported birds = b
Then, We can formulate;
Total number of birds = Stayed birds + Transported birds
Substitute all the values, we get;
⇒ 68 = 24 + b
Therefore,
The correct expression to show the species of transported birds will be;
⇒ b + 24 = 68
Where, b is the number of transported birds.

Answer:
∠ 2 = 140°
Step-by-step explanation:
the left base angle in the triangle and 110° are a linear pair and sum to 180°
base angle + 110° = 180° ( subtract 110° from both sides )
base angle = 70°
the 2 sides of the triangle are congruent so Δ is isosceles with base angles congruent.
the vertex of the Δ is then
(180 - 70 - 70)° = 180° - 140° = 40°
the vertex and ∠ 2 are a linear pair and sum to 180° , that is
∠ 2 + 40° = 180° ( subtract 40° from both sides )

Step-by-step explanation:
she can build 5 in 6 minutes. 6 × 10 is 1 hour
so you would do 5 × 10 = 50
then multiply 50 × 10 hours = 500 toys
Answer:
Patricia will build 500 toys in 10 hours
Step-by-step explanation:
5 toys ? toys
--------- = ----------
6 minutes 10 hours
so we would turn the hours into minutes which would be
600 minutes.
5 toys ? toys
--------- = ----------
6 minutes 600 mins

what is a set of relations
The relation is the relationship between two or more sets of values. Suppose, x and y are two sets of ordered pairs. If set x has a relation with set y, then the values of set x are called domain whereas the values of set y are called range. A relation from a set A to a set B is a subset of A×B. Hence, a relation R consists of ordered pairs (a,b), where a∈A and b∈B. If (a,b)∈R, we say that is related to, and we also write aRb. A connection between the elements of two or more sets is a relation. The sets must be non-empty. A subset of the Cartesian product also forms a relation R. A relation may be represented either by the Roster method or by the Set-builder method.
Find the slope of the line that contains the given point
Answer:
(2, 1) and (4, 2): [tex]\frac{1}{2}[/tex]
(-4, 5) and (-3, -7): [tex]-12[/tex]
Step-by-step explanation:
Hello! Let's help you with that problem there!
So we know that in a slope intercept form, it is depicted as [tex]y=mx+b[/tex]. There are two ways to essentially find m, which is slope in this case. The first method is the [tex]\frac{rise}{run}[/tex] method. This is typically used when you have a graph to look off from and it's just a matter of counting the displacement from one point to another.
However, there is another way to find the slope given 2 points and that is what we are going to do here, since we have no graph to reference and have all the relevant information to find the slope using this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
With this formula, we can plug in the coordinate values and solve for the slope!
(2, 1) and (4, 2):
[tex]m=\frac{2-1}{4-2}[/tex]
[tex]m=\frac{1}{2}[/tex]
Therefore, the slope of these points is [tex]m=\frac{1}{2}[/tex]
(-4, 5) and (-3, -7):
[tex]m=\frac{-7-5}{-3-(-4)}[/tex]
[tex]m=\frac{-12}{1}[/tex]
[tex]m=-12[/tex]
Therefore, the slope of these points is [tex]m=\frac{-12}{1}[/tex] or [tex]m=-12[/tex]
