What property was applied to solve the equation below?

0.36 x = negative 1.8
0.36 (divided by 0.36) x = negative 1.8 (divided by 0.36)
x = negative 5

Answers

Answer:

Division property

Step-by-step explanation:

The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.

The goal of dividing an equation is to isolate the unknown variable on one side.

For example, let the equation be:

2×x=10

Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:

2×x÷2=10÷2

Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.

Find the diameter of a circle if its circumference is 53.38 inches. Use π ≈ 3.14. Round to the nearest hundredth

Answers

Answer:16.9

Step-by-step explanation:

We know that the formula for C= πd. So to find the diameter of a circle we work backwards from its circumference. Division is the opposite of multiplying, so we divide its circumference by π: 53.38 / 3.14 = 17. To fully check: C= πd = π(17) = 53.38. The diameter is 17 inches. Hope this helps!

A lot of kids look up to heroes because they save lives, they are wonderful role models, and they are great examples of good people. Some of the main heroes we see today are police officers, firefighters, doctors, and many more. I have made up my own hero. His name is Reyota and he gets his powers from the greek gods. He is very powerful and he can harness his powers from any humans, or objects. Reyota goes on a magical journey to defeat his evil spirits. He uses his powers to guide him through the way. His mother is being held captive and he is trying to save her. This makes him a hero because he goes on a journey to help someone in need that he truly cares about. One day a hero was born, Reyota. He was always making friends and cherished his mom so much. He was playing with his friend, Michael and they were playing in the backyard and Reyotas mom was bringing them lemonade since it was really hot outside. Kids I have some lemonade for you guys!, Reyotas Mom exclaimed. The kids ran from the treehouse to get their lemonade, thanks Mom! Reyota exclaimed. The children had loved the taste of the lemonade. Wow, your Mom makes fantastic lemonade, Michaeal said. Thanks! Ill tell her later., Reyota replied. They finished up the lemonade before they were about to head back to the treehouse. Then suddenly a black hole appeared out of thin air. Reyotas Mom had come outside to check on the children but she was pulled into the black hole by this transparent thing that had a weird, domestic face. She had been gone for over a week. Reyota kept thinking of ways to save her but nothing worked. He went outside to get his mail but then a huge cloud struck over him. BOOM!, The thunder roared. Reyota was sunken into the clouds. He saw a giant person standing there, watching him. He also saw a big city and the air smelled wonderful. Hello Reyota, Im Zeus, God of Thunder. I noticed that your mom was captured., Zeus said. Well yes, but what do you want with me?, Reyota asked. Your special and your mom was captured by your evil spirits., Zues said. I'm special? What do you mean by that?, Reyota asked. What I mean by that is, is that you were born with a special power. Didnt your mom tell you?, Zeus asked. No but thats really cool! But what are my powers exactly?, Reyota begged. Your powers are out of this world. You can fly and harness anyones powers around you., Zeus explained. So Zeus trained Reyota how to fight and how to use his powers so he could save his Mom. Reyota had grown to be older and he became best friends with Zeus. Reyotas mom had been stuck in the underworld by Reyotas evil spirits. He went on a quest to the underworld to rescue his mom. He was walking in a strange forest when he came across this hairy beast. Who are you and what are you doing here!, The beast demanded. Im looking for my mother, Reyota said. Oh The beast said. She was captured by my evil spirits. Reyota mentioned. The beast showed Reyota a magic mirror that reveals the future. Reyota saw his mom being tortured. He was astonished but he thanked the beast for showing him what they were doing to his mother. He left the forest and he was ready to find his mother.Reyota found himself being in an ice kingdom. There was a huge ice castle. He thought to himself, how will I pass through this monster, I can do this. I just have to use my powers wisely. He touched the ground full of ice and he felt all tingly inside but he felt stronger, He fought the beast and defeated him with ease. He went into the castle but he saw these blue creatures. The creatures were called the snow keepers. He asked them how to get through the underworld but they said he had to speak to the queen. He walked up to her and he saw her sitting in a tall, enormous, icy, throne. He bowed to her to show his respect. He asked her how to get to the underworld and she said, walk down to the third corridor and take two steps to the left and you should find a portal to the underworld, The Queen said. Thank you, Reyota replied. He followed her instructions and made it out of the castle. He entered it and his mom was screaming. He removed the chains that were tied around her neck. He rescued her and took her back to earth. Wow, thanks for rescuing me son. she said as they were flying in the air. I missed you so much mom he said. I missed you too, she replied. Reyota flew back into the clouds after he kissed his mom goodbye. This was truly his new life. Reyota was brave. He saved his mom and his plan went through its course. This makes him a hero because he goes on a journey to help someone in need that he truly cares about. Reyotas real journey had just begun.
