Please help! I think of a number, I double it, and then add 3. The result is 19. Write this in the form of an equation and then solve the equation to find the number I was thinking of.

Answers

Answer 1

Answer:

8

Step-by-step explanation:

Y×2+3=19

19-3=16

16÷2=8

You subtract the 3 first to get what the number was when doubled. After getting that number you would divide it by 2 to get the number that you thought of.

Can sides of a triangle have lengths 3,4,9

Answers

Answer:

yes

Step-by-step explanation:

No, the lengths 3, 4, and 9 cannot form the sides of a triangle.

What is Triangle Inequality?

The triangle inequality is a fundamental geometric principle that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

We have sides as 3, 4 and 9.

For a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side.

In this case, let's check if this condition is satisfied:

3 + 4 = 7

7 is less than 9

Therefore, these lengths do not satisfy the triangle inequality theorem, and a triangle cannot be formed with side lengths 3, 4, and 9.
