What is the value of x?

Mathematics

Since angle x and the angle measure given are on the same line, they have to add up to 180 degrees. So, to start this problem, take what is given and set it equal to 180 degrees. 

x - 36 + x = 180

Now simplify the equation. 

x - 36 + x = 180   ******* Add 36 to both sides.

x + x = 216          ******* Now add together the x's

2x = 216              ******* Divide both sides by 2.

x = 108

108 degrees is your answer, but you should still go back and check your work. Plug in the value of x to see if it works in the equation. 

x - 36 + x = 180 **** plug in 108 for x

108 - 36 + 108 = 180 ****** simplify to see if it equals 180

72 + 108 = 180

180 = 180 

******** This answer does work because when x is plugged back into the equation, both sides are equal. **********************************************

x = 108 degrees

Shiloh has to earn at least $200 to meet her fundraising goal. She has only 100 cakes that she plans to sell at 5 dollars each.
kakasveta [241]
Here is the inequality you can enumerate:

5x >= 200, this means the money you sold for cakes must be larger or equal to your goal

x <= 100, this means you cannot sell more than 100 cakes, because you only have 100 cakes

Solve for them, you will get: 40 <= x <= 100

Amanda is 25 years old. in 5 years she will be twice as old as simone how old i simone
Nadya [2.5K]
We could use Algebra for this question but it’s quite simile so won’t need it. If Amanda is 25, when we add on 5 years she’ll be 30. Now it says when she’s 30, she will be twice as old as Simone. Implying that Simone will be half of Amanda’s age. In this case 30/2 = 15. So Simone must be 15.
