If a+b/a-b=5/3, what are the following ratios? 2a-4b/a-2b
Answers
Answer:
Hope this may helps you
The value of ratios (2a - 4b) / (a - 2b) is,
⇒ 2
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
The value is,
⇒ (a + b )/ (a-b) = 5/3
Now, We get;
⇒ a + b = 5
⇒ a - b = 3
Hence, By solving above equation,
a = 4
b = 1
Thus, The value of ratios (2a - 4b) / (a - 2b) is,
⇒ (2a - 4b) / (a - 2b)
⇒ (2 × 4 - 4 × 1) / (4 - 2 × 1)
⇒ (8 - 4) / (4 - 2)
⇒ 4 / 2
⇒ 2
Thus, The value of ratios (2a - 4b) / (a - 2b) is,
⇒ 2

Which graph shows the following system of equations and its solutions? -0.1x-0.3y=1.2 and 0.2x-0.5y=2
Answers
Answer:
Option b is the correct answer as both the equations are true for given solution.
Step-by-step explanation:
Given equations are:
-0.1x-0.3y=1.2
0.2x-0.5y=2
We can observe each graph and find the point that is the solution and put the point in the equations to know if that point is the solution
For option A:
(0,4)
Putting x=0 and y = 4 in both equations
[tex]-0.1(0)-0.3(4)=1.2\\0-1.2 =1.2\\-1.2 \neq 1.2\\0.2(0)-0.5(4)=2\\0-2 = 2\\-2 \neq 2[/tex]
This is not the correct answer as both equations are not true with this solution
For Option B:
(0,-4)
Putting x = 0 and y = -4 in both equations
[tex]-0.1(0)-0.3(-4)=1.2\\0+1.2 = 1.2\\1.2 = 1.2\\0.2x-0.5y=2\\0.2(0)-0.5(-4) = 2\\2 = 2[/tex]
Both equations are true for (0,-4) hence it is the solution of the system.
For Option C:
(4,0)
[tex]-0.1(4)-0.3(0)=1.2\\-0.4-0 = 1.2\\-0.4 \neq 1.2\\0.2x-0.5y=2\\0.2(4)-0.5(0) = 2\\0.8 \neq 2[/tex]
Not true for both equations
Hence,
Option b is the correct answer.
Given the side lengths of 20,23 and 41, determine whether the triangle is acute, right, obtuse, or not a triangle.
Answers
=====================================================
Explanation:
In this case, a triangle is possible since adding any two sides leads to a sum larger than the third side
20+23 = 43 is larger than 4120+41 = 61 is larger than 2323+41 = 64 is larger than 20I'm using the triangle inequality theorem here.
----------------------------
To determine what kind of triangle we have, we'll use the converse of the Pythagorean theorem. Specifically, we'll use a corollary of it.
Consider a triangle with sides a,b,c. Let c be the longest side.
We have three possible cases:
If a^2+b^2 = c^2, then we have a right triangleIf a^2+b^2 > c^2, then the triangle is acute.If a^2+b^2 < c^2, then the triangle is obtuse.For this problem, we have a = 20, b = 23, c = 41.
We see that a^2+b^2 = 20^2+23^2 = 929 and c^2 = 41^2 = 1681.
In short, a^2+b^2 = 929 and c^2 = 1681.
Since 929 < 1681, this means a^2+b^2 < c^2.
Therefore, this triangle is obtuse.

Answer:
4x+2 =90°
3x+2=68°
x=22
Step-by-step explanation:
The interior angles of a triangle always add up to 180° so you will add the angles together and set them equal to 180° to solve for x. You will find that x should be equal to 22. Plug 22 into each equation to find the angle measure.
