Answer:

m=75

percentage= 32

part= 24

whole= 75

Step-by-step explanation:

To get m, you divide 18 by .24(since it's the decimal form of 24%) and you get 75.

The part/whole part I'm not exactly sure about but since it's 24% of 75, I'm guessing the part is 24 and the whole is 75 and that's the entire thing we are working with here.

To get the percentage, we use the 24/75 fraction. We have to get the demonator to 100 but since 75 can't be multiplied by anything to get to 100, we have to simplfy the fraction so the demonator can go into 100. I divided the fraction by 3 since that would get the fraction to 8/25. 25 can go into 100 if we multiply by 4 so that's what you do. The ending fraction would be 32/100 after multiplying the numerator and demonator by 4(8/24). So the percentage would be 32% or 32/100.

I have never done this is my life but it is similar to what I have done so please correct me if I am wrong. I hope this helped you and I am incredibly sorry if it is wrong.

Can more than one triangle be drawn with one side length of 4 centimetres and 2 centimetres and an included angle of 50°? Explain.

Answers

Answer: No .

Step-by-step explanation:

If we make two triangles with lengths of 4 centimeters and 2 centimeters and an included angle of 50°, then by SAS congruence postulate both triangle will be congruent.

According to the definition of congruence , if two shapes are congruent then they have equal size and shape.

i.e. they look exactly same.

It means only one triangle is possible with the given measurement .

SAS congruence rule : It says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then we can say that these two triangles are congruent.

1) It’s true because -5 is way smaller than 3. All the negatives are below the 0 and everything below the 0 is lower than everything above the 0.

2) false. it’s false because in order -5 isn’t even close to 3

3) false.. It’s false because when you have those 2 line that are covering the -5 that means it’s “transforming” into a positive number. So therefore it’s would be 5>3 that would make it true.

4) True. it’s true because like I said the to lines mean the absolute value of something. So it’s being switch to a positive number

What is 4x +2 = 9x + 5

This is a challenge whoever gets it right gets brainly why not

Answers

Question :-

What is 4x +2 = 9x + 5

____________________

Solution :-

Given Information :-

4x + 2 = 9x + 5

To Find :-

The value of x

Calculation :-

⇒ 4x + 2 = 9x + 5

Now, subtract 2 from both Left Hand Side and Right Hand Side to eliminate + 2 in Left Hand Side,

⇒ 4x + 2 - 2 = 9x + 5 - 2

⇒ 4x = 9x + 3

Now, subtract 9x from both Left Hand Side and Right Hand Side to eliminate 9x in Right Hand Side,

⇒ 4x - 9x = 9x - 9x + 3

⇒ - 5x = 3

Now, Transpose - 5 to Right Hand Side,

⇒ x = [tex] \sf \frac{ 3}{ - 5} [/tex]

∴ x = [tex] \sf \frac{ 3}{ - 5} [/tex]

____________________

Final Answer :-

Value of 'x' is [tex] \sf \frac{ 3}{ - 5} [/tex].
