Misha solves the following system of equations using the substitution method.
y=5−2x
3x−y=15
What is the single-variable equation she solves after substituting?
A. 3(5+x)=5−2x
B. 15+3x=5−2x
C. 3x−(5−2x)=15
D. 3x−5−2x=15
Answer:
C
Step-by-step explanation:
The single equation of the system of equation y=5−2x and 3x−y=15 by substitution will be 3x−(5−2x)=15 thus option (C) will be correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given system of equations,
y = 5 − 2x
3x − y = 15
Substitute y = 5 - 2x into 3x − y = 15
3x - (5 - 2x) = 15
Hence "The single equation of the system of equation y=5−2x and 3x−y=15 by substitution will be 3x−(5−2x)=15".

A farmer wanted to estimate how many moles were living on his property, so he marked 24 of them with tags. A few weeks later, the farmer drove around his property and noticed 18 tagged moles out of the 330 moles he counted. To the nearest whole number, what is the best estimate for the mole population?
Answer:
The answer is 70 moles
Step-by-step explanation:
For the farmer,
Total no of Moles = 330
No of marked moles with tags = 24
No of unmarked moles = 330 - 24 = 306
Few weeks later,
No of tagged moles found = 18
No of tagged moles not found,
= marked moles with tags - tagged moles found
= 24 - 18 = 6
Therefore, if for every 24 tagged moles, there are 6 moles found,
288 tagged moles = 24 X 12 (lots) = 288
For moles found = 6 X 12 (lots) = 72
To the nearest whole number,
The best estimate for the mole population would be 70 moles

The set notation of the numbers is {x | x < 50 ∪ x > 50}
How to determine the set notation of the numbers?The set is given as
The set of all real numbers less than 50 or greater than 50
Let the number be represented by x
So, we have
x less than 50 or x greater than 50
When represented as an inequality, we have
x < 50 or x > 50
Using set notation, we have
{x | x < 50 ∪ x > 50}
Hence, the set notation of the numbers is {x | x < 50 ∪ x > 50}

When you find the volume of a triangle, remember to do this:
Step-by-step explanation:
Multiply the base times the height, then divide by two.
:)
The mistake is in the second triangle and is noticeable at first because the length of the leg is longer than the length of the hypotenuse.
Since this is a 30 60 90 triangle, you can use the properties that apply to them. I'm assuming that the leg with the length of 62ft is the given side. Using the rules, we know that x/2 is 62 (since the properties of a 30 60 90 triangle state that the shortest side is x/2). In order to find the hypotenuse (which is x), we can multiply both sides of the equation x/2 = 62 to get x = 124. To find the second leg, we need to use sqrt(3)*x/2, which when you plug in 124, gives 107.39. Andrea just switched the lengths of the second leg and the hypotenuse on accident.

Answer:
x = [tex]130^{o}[/tex]
Step-by-step explanation:
The given figure is a trapezium which is a quadrilateral with four sides.
But,
Sum of angles in a quadrilateral = (n - 2) x 180
where n is the number of sides.
For a quadrilateral, n = 4. So that,
Sum of angles in a quadrilateral = (4 - 2) x 180
= 2 x 180
= [tex]360^{o}[/tex]
The sum of angles in a quadrilateral is [tex]360^{o}[/tex].
Thus,
[tex]158^{o}[/tex] + [tex]51^{o}[/tex] + [tex]x^{o}[/tex] + [tex]21^{o}[/tex] = [tex]360^{o}[/tex]
[tex]x^{o}[/tex] + [tex]230^{o}[/tex] = [tex]360^{o}[/tex]
[tex]x^{o}[/tex] = [tex]360^{o}[/tex] - [tex]230^{o}[/tex]
= [tex]130^{o}[/tex]
The value of x is [tex]130^{o}[/tex].

A. 4.0784% compounded monthly
B. 4.0792% compounded quarterly
C. 4.0730% compounded daily

Answer:
The answer is "Option C"
Step-by-step explanation:

→r = rate
→ n = compounded value
In choice a:
When compounded is monthly [tex]4.0784\%[/tex]
[tex]n = 12[/tex]
[tex]\to (1+ \frac{0.040784}{12})^{12} = 1.0403-1 = 0.0403[/tex]
In choice b:
When compounded is quarterly[tex]4.0792\%[/tex]
[tex]n = 3\\\\\to (1+ \frac{0.040792}{12} )^{3} = 1.0102-1 = .0102[/tex]
In choice c:
Whenn compounded is daily [tex]4.0730 \%[/tex]
[tex]n = 365\\\\\to (1+ \frac{0.040730}{12})^{365} = 3.328-1 = 2.328[/tex]
In choice d:
When compounded is semiannually[tex]4.0798\%[/tex]

Let gbe a function such that g(x) = -2r + 5 and is defined on the domain (-1,3) State the range of this function in interval notation.
Answer:
The range interval is: (7, -1)
Step-by-step explanation:
Given the function
g(x) = -2r+5
As the domain is (-1, 3)Let us put the domain values in the interval (-1, 3)
Putting x = -1
g(x)=-2r+5
= -2(-1)+5
= 2+5
= 7
Putting x = 0
g(x)=-2r+5
= -2(0)+5
=0+5
= 5
Putting x = 1
g(x)=-2r+5
= -2(1)+5
=-2+5
= 3
Putting x = 2
g(x)=-2r+5
= -2(2)+5
=-4+5
= 1
Putting x = 3
g(x)=-2r+5
= -2(3)+5
=-6+5
= -1
Thus the range interval is: (7, -1)

Given , expression 7 x 8(9+8) - 6 x 7 + 2(77 x 8) - 7 + 1092(2010 x 0.1134) + 17 - 27.
Apply BODMAS to solve the expression.
B = Bracket
O = of
D = Division
M = Multiplication
A = Addition
S = Subtraction
Following the same order,
7 x 8(9+8) - 6 x 7 + 2(77 x 8) - 7 + 1092(2010 x 0.1134) + 17 - 27
= 952 - 42 + 1232 - 7 + 248903.928 + 17 - 27
