If f(x)=-2x+9, then find the value of the x value that makes F(x)=-22

Answers

Answer 1
-22 = -2x + 9
-31 = -2x
-31/-2 = x
x = 15.5 
Answer 2
Final answer:

To solve for the value of x where f(x) = -22 for the function f(x) = -2x + 9, we set up the equation -2x + 9 = -22, subtract 9 from both sides, and then divide by -2, resulting in x = 15.5.

Explanation:

To find the value of x that makes f(x) = -2x + 9 equal to -22, we need to set the function equal to -22 and solve for x.

-2x + 9 = -22

First, subtract 9 from both sides:

-2x = -22 - 9

-2x = -31

Next, divide both sides by -2 to solve for x:

x = 31 / 2

x = 15.5

The value of x that makes f(x) equal to -22 is 15.5.

Maria has c boxes of 10 pencils. The teacher gives her another 20 pencils. How many pencils does she have altogether?

Answers

10c+20

Hope this helps :)
the equation to your question would be P =10(c)+20. meaning 10 pencils in each box multiplied by the number of boxes (c) plus the 20 pencils the teacher gives her will equal the number of pencils (P) she has altogether. (C stands for the number of boxes and P stands for pencils)

    so lets say she has 3 boxes. well, c stands for boxes soooo...... all you have to do is plug in 3 were c is. giving you this equation P = 10(3)+20. then all you have to do is solve.  P = 10(3)+20
         10 times 3 = 30 so      P = 30+20
then add 30 and 20             P = 50           she has 50 pencils altogether 

      (remember this is just an example, 50 pencils is NOT the answer to your question. but you can use the equation i gave you to find your own answer!) :) Hope this helps!!

find the area of the large rectangle by multiplying the number of rows by the number of squares in each row.

Answers

The area is 21 if it is the entire rectangle if it is just the larger part of the rectangle then the area is 15.
Final answer:

The area of a rectangle is calculated by multiplying the number of rows by the number of squares in each row, which represents the length and breadth respectively.

Explanation:

The area of a rectangle can be calculated by multiplying the number of rows by the number of squares in each row. This corresponds to the multiplication of the length (number of squares in each row) and the breadth (number of rows). For example, if you have a rectangle made up of 4 rows and each row consists of 5 squares, the area would be 4 rows * 5 squares per row = 20 squares.

In real-life applications, for instance, if calculating the area of a floor that is 12.0 m², and the uncertainty is 3 percent (expressed as an area this is 0.36 m² - rounded to 0.4 m² assuming measured to a tenth of a square meter). Therefore, understanding the concept of calculating area is highly important.

I am climbing up a mountain that has a lake at the bottom. The lake is 100 feet deep. If I have climbed one third of the way up the mountain and I am currently at 220 feet above lake level, what is the elevation change from the bottom of the lake to the top of the mountain?

Answers

Final answer:

The total elevation change from the bottom of the lake to the top of the mountain is 760 feet. This calculation comes from multiples and subtraction.

Explanation:

You've got a neat problem here involving subtraction and multiplication. It's all to do with altitude and elevation change. You have climbed one-third of the way up the mountain and are currently 220 feet above lake level. This means that a third of the mountain's height from the lake's surface is 220 feet. To find the total height from the lake to the top of the mountain, we can do a simple multiplication:

1. 3 (representing the whole mountain) × 220 feet (one-third of it) = 660 feet.

However, you asked for the elevation change from the bottom of the lake to the top of the mountain. The lake is 100 feet deep, so we add this to our total:

2. 660 feet (mountain height) + 100 feet (lake depth) = 760 feet.

So, the elevation change from the bottom of the lake to the top of the mountain is 760 feet.

Final answer:

The total elevation change from the bottom of the lake to the top of the mountain is 760 feet.

Explanation:

To answer the question, we need to understand that if the student is already 220 feet above the lake, and this represents one third of the way up the mountain, we can use this information to find the total elevation change from the lake bottom to the top of the mountain. We first need to calculate how high the mountain is above the lake by dividing 220 feet by one third (or 0.33), which gives approximately 660 feet. However, this does not include the depth of the lake. As the lake is 100 feet deep, we need to add this to our previous value to get the total elevation change. This gives us an elevation change of 660 feet + 100 feet = 760 feet from the bottom of the lake to the top of the mountain.

B. On Sunday, 1/16 of the people who visited were senior citizens, 3/16 were infants, 3/8 were children, and 3/8 were adults. How many of each group visited the zoo on Sunday?

Answers

You can add the numbers of those people to come up with the total.

Answer: Hello there!

we know that the zoo had an equal number of visitors on Saturday and Sunday, if the total number of visitors in the weekend is 32096, then the visitors in each day are: 32096/2 = 16048.

a) on Saturday, 1/8 of the people who visited were senior citizens, 1/8 were infants, 1/4 were children, and 1/2 were adults.

if we want to know the amount of each, then:

the amount of senior citizens are: (1/8)*16048 = 2006  

the amount of infants are: (1/8)*16048 = 2006

the amount of children is: (1/4)*16048 = 4012

the amount of adults are: (1/2)*16048 = 8024

b) On Sunday, 1/16 of the people who visited were senior citizens, 3/16 were infants, 3/8 were children, and 3/8 were adults.

the amount of senior citizens are : (1/16)*16048 = 1003

the amount of infants are: (3/16)*16048 = 3009

the amount of children is: (3/8)*16048 = 6018

the number of adults is also: (3/8)*16048 = 6018

Show work if can please!
Answer:

Answers

1.

Answer

[tex]Lola=\frac{203}{537}[/tex]

[tex]Ahmed=\frac{154}{537}[/tex]

[tex]Tommy=\frac{60}{179}[/tex]

Explanation

To find fraction of the total sales for each salesperson, we just need to divide the amount sold by each person by the total sales.

First, we are going to find the total sales:

$2030 + $1540 + $1800 = $5370

Now we can divide the amount sold by each salesperson by $5370:

[tex]Lola=\frac{2030}{5370} =\frac{203}{537}[/tex]

[tex]Ahmed =\frac{1540}{5370} =\frac{154}{537}[/tex]

[tex]Tommy=\frac{1800}{5370} =\frac{60}{179}[/tex]

We can conclude that Lola sold [tex]\frac{203}{537}[/tex] of the total sales, Ahmed sold [tex]\frac{154}{537}[/tex] of the total sales, and Tommy sold [tex]\frac{60}{179}[/tex] of the total sales.

2.

Answer

Lola = $37.80

Ahmed = $28.68

Tommy = $33.52

Explanation

We need to divide $100 bonus according of the fraction of the total sales sold by each salesperson; to do so, we need to multiply $100 by the fraction of the total sales for each salesperson:

[tex]Lola=\frac{203}{537}*100=37.8026[/tex]

And rounded to the nearest cent:

Lola = $37.80

[tex]Ahmed=\frac{154}{537}*100=28.6778[/tex]

And rounded to the nearest cent:

Ahmed = $28.68

[tex]Tommy=\frac{60}{179}*100=33.5195[/tex]

And rounded to the nearest cent:

Tommy = $33.52

We can conclude that of the $100 bones, Lola received $37.80, Ahmed $28.68, and Tommy $33.52

bonnie has set of 40 tiles that she bought while traveling in South Africa. What is the largest frame size (on each side) that she can make with these. tiles? Will she use all of her tiles?

Answers

Final answer:

Bonnie can make a frame with sides measuring 20 tiles and 2 tiles, using all of her 40 tiles.

Explanation:

To find the largest frame size that Bonnie can make with her 40 tiles, we need to determine the factors of 40. A factor is a number that divides evenly into another number. The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40.

To create a frame, Bonnie needs two sides with lengths that multiply to give 40. The largest frame size will have sides of length 20 and 2, which can be achieved by placing the tiles in a rectangular shape.

Therefore, Bonnie can make a frame with sides measuring 20 tiles and 2 tiles, using all of her 40 tiles.
