Answer:
The true statement is AB > CA > BC ⇒ D
Step-by-step explanation:
In any triangle, the longest side in length is the opposite to the greatest angle in the measure, and the shortest side in length is opposite to the smallest angle in the measure.
Let us solve the question
∵ ABC is a triangle
∵ m∠A = 36°
∵ m∠B = 45°
∵ m∠C = 99°
→ That means C is the greatest angle and A is the smallest angle
∴ ∠C is the greatest angle and ∠A is the smallest angle
∴ The arrange of the measures of the angles is m∠C > m∠B > m∠A
∵ AB is the opposite side of ∠C
∴ AB is the longest side
∵ BC is the opposite side of ∠A
∴ BC is the shortest side
∵ CA is the opposite side of ∠B
∴ The arrange of the lengths of the sides is AB > CA > BC
∴ The true statement is AB > CA > BC

Step-by-step explanation:
Ren was trying to solve a system of linear equations. He correctly argued that he could replace one equation by the sum of that equation and multiple of the other. He stated that this would produce a system that has the same solution as the original system.
To show this, Ren wrote down a system of equations. He them determined wich othe system of equations would have the same solution as the original system. Ren's original system is shown below.
Answer:
This what I got.

The solution of 1st and 2nd system of equations have solutions same as the main system of equations and 3rd is not same.
What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
The given equations are;
-2x-5y = -47........(i)
4x-2y = -2
We can simply it, and write;
2x-y = -1
y = 2x+1.....(ii)
Put equation (ii) in (i)
-2x-5(2x+1) = -47
-2x-10x-5 = -47
-12x = -42
x = 7/2
Put value of x in eq (ii)
y = 2(7/2)+1
y = 8
Therefore, the solution of main equation is (7/2, 8)
Solving the other three equations,
1) -14x+y = -41
or, y = -41+14x......(i)
2) 4x-2y = -2
or, 2x-y = -1
y = 2x+1....(ii)
Solving the equations,
2x+1 = -41+14x
12x = 42
x = 7/2
Put x = 7/2, in (ii)
y = 8
Therefore, the solution is (7/2, 8)
We get the solution of main equation is equal to this system of equation.
2) -2x-5y = -47......(i)
6x+3y = 45
or, 2x+y = 15.......(ii)
Solving the equation by elimination,
-4y = -32
y = 8
Put y = 8 in equation (ii)
2x+8 = 15
x = 7/2
Therefore, the solution is (7/2, 8)
Again, we get the solution of main equation is equal to this system of equation.
3) -2x-5y = -47.........(i)
8x-5y = -8.......(ii)
Solving the equations by elimination,
-10x = -39
x = 39/10
Since, value of x is not same as the value of x in main equation, that means, both the system of the equation do not have same solution.
Hence, we get that, the solution of 1st and 2nd system of equations have solutions same as the main system of equations and 3rd is not same.

What is the scale factor in the dilation?
Answer:
The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs.

Answer:
The value of x is 1
Step-by-step explanation:
Let us solve the question
∵ Δ PQR ≈ Δ FGH
→ From similarity, then their corresponding sides have an equal ratio
∴ [tex]\frac{PQ}{FG}[/tex] = [tex]\frac{QR}{GH}[/tex] = [tex]\frac{PR}{FH}[/tex]
∵ PQ = 3, QR = x + 3, PR = 2
∵ FG = 6, GH = 6x + 2, FH = 4
→ Substitute them in the ratios above
∴ [tex]\frac{3}{6}[/tex] = [tex]\frac{x+3}{6x+2}[/tex] = [tex]\frac{2}{4}[/tex]
→ By using cross multiplication between the first two ratios
∵ 3 × (6x + 2) = 6 × (x + 3)
∴ 3(6x + 2) = 6(x + 3)
∴ 3(6x) + 3(2) = 6(x) + 6(3)
∴ 18x + 6 = 6x + 18
→ Subtract 6x from both sides
∵ 18x - 6x + 6 = 6x - 6x + 18
∴ 12x + 6 = 18
→ Subtract 6 from both sides
∵ 12x + 6 - 6 = 18 - 6
∴ 12x = 12
→ Divide both sides by 12
∴ x = 1

Answer:
4(y+2) = 3(x+4) and 4y - 3x = 4
Step-by-step explanation:
The equation of the line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
Given the equation 3x - 4y = 7
Rewrite in slope intercept form
-4y = -3x+7
y = 3/4 x - 7/4
Slope = 3/4
Slope of the required line will also be 3/4 since they are parallel lines
Substitute the slope and the point into the equation above;
y - y0 = m(x-x0)
y +2 = 3/4 (x+4)
4(y+2) = 3(x+4)
4y + 8 = 3x+12
4y - 3x = 12-8
4y - 3x = 4
Hence the required equations are 4(y+2) = 3(x+4) and 4y - 3x = 4
Find the slope for this line.

One health club charges a $40 membership fee and $40 per month. Another club charges a $100 membership fee and $25 per month. Write and solve an equation to find the number of months that it will take for the two health clubs to be equal
Answer:
After 4 months, the charges will be same.
Step-by-step explanation:
Membership charges of club one = $40
Per month charges = $40
Let,
x be the number of months
y be the total amount
y = 40x + 40
Membership charges of club two = $100
Per month charges = $25
y = 25x + 100
For equal charges, both equations will be same
40x + 40 = 25x + 100
40x - 25x = 100 - 40
15x = 60
[tex]\frac{15x}{15}=\frac{60}{15}\\x=4[/tex]
Therefore,
After 4 months, the charges will be same.
