30°



60°



90°



180°

Answers

Answer: [tex]60^{\circ}[/tex]

Step-by-step explanation:

x + 2x + 3x = 180 [angles in a triangle add to 180 degrees]6x = 180 [combine like terms]x = 30 [divide both sides by 6]

So, [tex]\angle C=2(30)=\boxed{60^{\circ}}[/tex]

Answers

Answer: 41

Step-by-step explanation:

The horizontal line beneath the angle created is always 180 degrees. Because you are given two equations for each angle created, simply write: 180= (3x-3) +(x+19). This gives you 4x+16=180, of which you subtract 16 to 180 which gives you 164. Finally, divide both sides by 4: 4x/4=164/4 and you will get 41. Hopefully I was of aid to you.

Answers

Answer:

[tex]\frac{5}{6}[/tex]

Step-by-step explanation:

Hi there!

We are given the following expression:

[tex]\frac{1}{6}[/tex] ÷[tex]\frac{1}{5}[/tex]

And we would like to solve it

Whenever we are dividing fractions, we are actually multiplying the first fraction (in this case, 1/6) by the reciprocal of the second fraction (in this case, 1/5), which is the "flipped" version of that fraction; the value that is in the numerator becomes the value in the denominator, and the value in the denominator becomes the value in the numerator.

So the reciprocal of 1/5 is 5/1, or 5/1

So we will multiply 1/6 by 5

[tex]\frac{1}{6} * 5 = \frac{5}{6}[/tex]

The fraction is in the simplest form; 5/6 is the answer.

Hope this helps!

1/6 divided by 1/5
When dividing fractions we keep the first fraction the same , change the sign to multiplication and flip second fraction. Some teachers use KCF (keep change flip) as a way for students to remember .
So let’s do it :
1/6 x 5/1 = 5/6
Your answer is 5/6

After using the linear equations method we will get 1.76.


What is linear equations?
An equation is said to be linear if the highest power of a variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the standard form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present. A linear equation is one that has a degree of 1 as its highest value. No variable in a linear equation, then, has an exponent greater than 1. A linear equation's graph will always be a straight line.

How to calculate question by adding their values in the given equation?

firstly, the given equation is: [w2x-3]/10z

Now putting all the values in the given equation:

___

f(1) = 4(1^2) = 4

f(2) = 4(2^2) = 16

f(3) = 4(3^2) = 36

Solve the inequality
-5/2(3x-2)<6-2x.
Show and explain every step.

Answers

Answer:

its true the answer is true but would u need a whole Paragraph like an explanation I could make one for you.

The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

What is inequality?

inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

Given inequality will be solved as below:-

( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x

Multiply the other hand by 2 and solve further.

( - 5  ) ( 3x - 2 ) < 2 ( 6 - 2x )

( - 5  ) ( 3x - 2 ) < ( 12 - 4x )

Take like terms to the same side and solve.

-15x + 30 < 12 - 4x

-15x + 4x < 12 - 30

-11x < - 18

x < 18 / 11

Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).
