Solve for X in the following equation. 473 = 15X + 23

To begin solving for X, we must isolate the X. This means putting all of the constants (regular numbers) on one side of the equal sign and the X on the other side. Step 1 is subtracting the constant 23 from both sides, so we can focus on X. 23 - 23 = 0 and 473 - 23 = 450. The equation that remains is 450 = 15X. Step 2 is to divide both sides by 15, so we can completely isolate the X. 15X divided by 15 = X and 450 divided by 15 = 30. The equation that remains is 30 = X. Therefore X = 30.

Sarah goes to the store to buy a new dress. She has $50. The dress costs $35, with a 9% sales tax. How much money will Sarah have after she buys the dress?

To first solve this problem, we will need to determine what answer we are looking for. Although the problem would like us to calculate the price of the dress, we need to find how much money is leftover after the purchase. We will begin by converting 9% into a decimal so we can multiply. 9% as a decimal is equal to 0.09. We will then multiply 35 by 0.09. 35 x 0.09 = 3.15. This is the tax price. We will now add the tax price to the original price. 35 + 3.15 = 38.15. Our last step is to subtract the total from the amount of money Sarah had. 50 - 38.15 = 11.85. Therefore, Sarah has $11.85 leftover after buying the dress.

What are the fundamental differences between Piaget's view of childhood development and Vygotsky's view of childhood development? Which is most accurate?

Piaget viewed childhood development through biological stages. Each of these stages had specific attributes and a timeline. Piaget theorized that these stages were predictable and accurate to most children. Vygotsky theorized that childhood development was not molded through biology, but the environment surrounding the child. Vygotsky viewed socialization, culture, and language as the highest contributing factors to childhood development. While both theories have remained prominent throughout the years, the truth lies somewhere in between these two theories. The classic question of nature vs. nurture cannot be answered definitively. In reality, the interaction of nature and nurture (biology and environment) most accurately explain the development of a child.
