Solve for x.
18 ÷ x = -2
x = _____
Answers
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
Answers
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?
Answers
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.

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.
Answers
Distance from house to school : (Under Absolute value) (x2-x1)^2 + (y2-y1)^2
( -4 - (-4) )^2 + (10 - 3 )^2 = 0 + 49 = Radical 49 = 7
Distance from house to grocery store : (using the same method) you get = Radical 1200 = 60
Distance from house to community center : (using the same method) =

Distance from house to school to grocery store is

Distance between the SC

A city is putting in a sand pit at the park. The length is an even, one-digit whole number, and
the width is 6.7 feet. Which explains the least and greatest possible areas for the sand pit?
A.
The least and greatest one-digit whole numbers are 1 and 9. Since 1 × 6.7 = 6.7 and
9 × 6.7 = 60.3, the least and greatest areas for the sand pit are 6.7 square feet and
60.3 square feet.
B.
The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 12.7
and 8 × 6.7 = 48.7, the least and greatest areas for the sand pit are 12.7 square feet
and 48.7 square feet.
C.
The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4
and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet
and 53.6 square feet.
D.
The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 14
and 8 × 6.7 = 56, the least and greatest areas for the sand pit are 14 square feet
and 56 square feet.
Answers
Answer:
Listen the number is an even one-digit, so that means all odd numbers that are one-digit numbers are out so that means number A is wrong so its between B, C, and D. If you read the answer thoroughly through B, C, and D you will find one of the 2 x 6.7 is wrong. To find the correct answer to 2 x 6 and if the sum of 2 x 6 is equal to your 2 x 6 you have the correct answer! Btw I forgot the exact answer but I know it was either B or C.
The correct option is The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4 and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet and 53.6 square feet.
What is Area of rectangle?The area of rectangle is the product of its length to its width.
i.e., Area of rectangle= length x width
Given:
The length is an even, one-digit whole number, and the width is 6.7 feet.
So, the least one digit even number is 2
then , the least area is = 2 x 6.7
= 13.4
and, the greatest one digit even number is 8
then , the greatest area is = 8 x 6.7
= 53.6
Hence, The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4 and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet and 53.6 square feet.
