Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 36. How old is each
sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer
Step-by-step explanation:
Let x be sister
equation = (x + 2x) = 36
= x = 36/3
= x = 12
kim is 2 times his sisters age so his age is 12×2 = 24

18 ÷ x = -2
x = _____
Answer:
-9
Step-by-step explanation:
18÷x = -2
18 = -2×x
18 = -2x
-9 = x
x = -9
Answer:
-9
Step by step explanation:
it can also be written as; 18 over x is equal to -2 over 1
you cross multiply to get 18 = -2x
then multiply through with -2; 18 over -2 = -2x over -2
you cross out; -2 cancels itself and -2 goes into 18 , -9 times
Therefore; the answer is -9
What is the value of y if x is 8 in the linear equation graphed?
A) 4
B) 5
C) 7
D) 13
Answer:
When x = 8, our y-value is equal to 13.
Step-by-step explanation:
We are given a graph that shows a linear relationship between our variables x and y.
In math, the slope-intercept form of an equation is written as:
[tex]\bullet \ y=mx+b, \text{where m is our slope and b is our y-intercept.}[/tex]
We also can note that there is another way to state a function: [tex]f(x)[/tex]. This replaces the y in the slope-intercept form and they can be used interchangeably.
[tex]\bullet \ f(x) = mx + b[/tex]
So, when we look at our graph, we can see that we have x-values on the bottom horizontal axis and y-values on the left vertical axis.
When we check this, we see that our x-values range from 0 to 9 and our y-values range from -2 to 14.
Therefore, we can see that since x is supposed to be equal to 8, we are going to draw a vertical line from x = 8 and see what point this intersects.
We see that the line would intersect the rightmost point and it is located between y = 12 and y = 14.
Therefore, we can just take the median of these two values and find our y value.
[tex]\displaystyle 12 + 14 = 26\\\\\frac{26}{2} = 13[/tex]
Therefore, y is equal to 13 and our answer is Choice D.

Explore the difference between volume and pitch as well as what causes them.
Sound Energy
Some ways that sound can be described are by loudness (or intensity) and by pitch. We can relate to loudness, because we often use the volume for our televisions or iPods™ to make the sound louder (more intense) or quieter (less intense). Pitch is a description of how high or low a sound is. Some sounds have a high pitch, like a chirping bird, while some have a low pitch, like a growling dog.
According to the article how is sound energy created?
Answer:
Sound energy is produced when a force causes an object or substance to vibrate. The energy is then transferred through the substance in waves, called sound waves.

Which multiplication expression is equal to 5/6÷1/2
A) 5/6 x 1/2
B) 6/5 x 1/2
C) 6/5 x 2/1
D) 5/6 x 2/1
Answer:
D
Step-by-step explanation:
Because of the phrase Keep Change Flip or KCF, you keep the first fraction as it is, change the sign to the opposite one, and flip the last fraction.
Answer:
The answer for the multiplication expression 5/6÷1/2 is 5/3 or 1 2/3.
This answer is equivalent to the expression D. 5/6 x 2/1.

It is recommended that you work this out on graph paper to help answer the questions. Sean plots the locations of 4 places on a coordinate grid as given below (It is recommended that you work this out on graph paper to help answer the questions.): His house is at (−4, 5). His school is at (−4, 3). The community center is at (6, 3). The grocery store is at (−4, −9). Part A: Use absolute values to calculate the distance in units from Sean's house to his school. Show your work. (4 points) Part B: Is the total distance from Sean's house to the school to the grocery store greater than the total distance from Sean's house to the school to the community center? Justify your answer.
The distances between two points are required.
The Distance from house to school to grocery store is greater than Distance to from house to school to community center.
The points are
[tex]H(-4,5)[/tex]
[tex]S(-4,3)[/tex]
[tex]C(6,3)[/tex]
[tex]G(-4,-9)[/tex]
The distance between the HS is
[tex]|HS|=\sqrt{(3-5)^2+(-4-(-4))^2}=2[/tex]
Distance between SG
[tex]|SG|=\sqrt{(-4-(-4))^2+(-9-3)^2}=12[/tex]
Distance from house to school to grocery store is
[tex]2+12=14[/tex]
Distance between the SC
[tex]|SC|=\sqrt{(6-(-4))^2+(3-3)^2}=10[/tex]
Distance to from house to school to community center
[tex]2+10=12[/tex]
So, the Distance from house to school to grocery store is greater than Distance to from house to school to community center.

In a grocery store, a $12 case of 24 soda is labeled, "Get a 20% discount." If you pay a 9.15% tax on the final price, how much will you pay per soda?
(please tell me how you did it)
Answer:
Soooo....
$0.44
Step-by-step explanation:
24 soda in one case and $12 for one case
20% off 12$ = 9.60
9.60 + 9.15% tax = 10.48
10.48 divided by 24
would could be about $0.44 each
