Answers

Answer:

Step-by-step explanation:

∠5 = ∠1             {Alternate exterior angles are congruent}

8x - 19 = 7x - 3

Add 19 to both sides

8x = 7x - 3 + 19

8x = 7x + 16

Subtract 7x from both sides

8x - 7x = 16

   x = 16

∠5 = 8x - 19

    = 8*16 - 19

    = 128 - 19

 ∠5 = 109

∠5 + ∠4 = 180     {linear pair]

109 + ∠4 = 180

         ∠4 = 180 - 109

∠4 = 71°

Step-by-step explanation:

5x+4=5x+4 is it one solution, no solution, or infinite solutions?

Answers

Answer: infinite solutions

Simplifying
5x + 4 = 5x + 4

Reorder the terms:
4 + 5x = 5x + 4

Reorder the terms:
4 + 5x = 4 + 5x

Add '-4' to each side of the equation.
4 + -4 + 5x = 4 + -4 + 5x

Combine like terms: 4 + -4 = 0
0 + 5x = 4 + -4 + 5x
5x = 4 + -4 + 5x

Combine like terms: 4 + -4 = 0
5x = 0 + 5x
5x = 5x

Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x

Combine like terms: 5x + -5x = 0
0 = 5x + -5x

Combine like terms: 5x + -5x = 0
0 = 0

Solving
0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.

Infinite solutions

Try to solve this equation:

5x+4=5x+4

Move all the variables to the left:

5x-5x+4=4

Do you see what I see?

4=4

We end up with a true statement. 4 does indeed equal 4. Hope this helps!

Answers

Answer:

-10

Step-by-step explanation:

The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.

how to use union in the real world?​

Answers

Answer:

To overcome such type of real world problems we use union. Unlike structures union occupies single memory location to store all its members. So, unions are helpful when you want to store value in single member from a set of members. Size of union is defined according to size of largest member data type.

Step-by-step explanation:

In union, all members share the same memory location. For example in the following C program, both x and y share the same location. If we change x, we can see the changes being reflected in y. #include <stdio.h> // Declaration of union is same as structures.
