Answer:

\$20,000

Explanation step-by-step:

Let

x represent Hermione's salary prior to the raise

Given:

100\%+5\%=105\%=105/100=1.05

Therefore, the equation that expresses this relationship is

1.05x=21,000

To find x, divide both sides by 1.05:

x=21,000/1.05

x=\$20,000

Some friends plotted the locations of their house on a map. brianna's house is at (1,6), Jordan's house is at (5,3). What is one
Zina [12379]
Let
A (1,6)------> denotes the location of <span>Brianna's house on a map
B </span>(5,3)------> indicates the location of
Jordan's house on a map

It’s clear that <span>One possible path from Brianna's residence to Jordan's home is a straight line (which represents the shortest distance) </span>

Utilizing a graphing tool
refer to the attached diagram

To calculate the distance between points A and B, we use:
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]
Ultimately, d=√25----> d=5 units

Thus, the distance from Brianna's house to Jordan's house is 5 units.

babunello [11817]

Response:

1. Closure

2. Distributive

3. Closure

Detailed explanation:

In this scenario, we are examining the properties that each equation demonstrates.

The first equation shows the closure property.

This indicates that whether we add in one direction or the other, the result remains unchanged. Therefore, we conclude that addition conforms to the closure property in this case.

The third equation also shows the closure property. Regardless of how we approach the addition for this equation, the outcome remains consistent.

The second equation displays the distributive property.

Each element within the parentheses is multiplied by the negative sign before we proceed with further calculations.
