Answer:
Step-by-step explanation:
first one: w-8 =5
reverse it- 8+5= 13 so 13-8= 5
second one: 5x-2
2x-2+3x << group together the x's
2x+3x=5x and you'll end up with 5x-2
last one: r/5=-9
again, reverse it- -9 x 5 = -45
a negative times a positive = a negative

Which expression is equivalent to 30 divided by (3+x)? F (3+x) divided by 30 G 30 divided by (x+3) H (3 divided by 30)+x J 30divided by 3 + 30 divided by x
Answer:
30 divided by (x+3)
Step-by-step explanation:
We need to find an expression that is equivalent to 30 divided by (3+x).
It will be in the form of x/y, where x is numerator and y is denominator.
Here, numerator = 20
Denominator = (3+x)
Expression :
[tex]\dfrac{30}{(3+x)}[/tex]
Hence, the correct option is (b) i.e. 30 divided by (x+3).
The expression is equivalent to 30/(3+x).
Hence, option G is correct.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.
And Using operations like addition, subtraction, multiplication, and division, a mathematical expression is defined as a group of numerical variables and functions.
Here given expression is:
30 divided by (3+x)
This expression can be written as:
30/(3+x)
Since (3+x) can not be factored,
Therefore,
We can not proceed further.
Hence,
The expression is equivalent to 30/(3+x) which is option G.

First rewrite the mixed number as an improper fraction:
-1 1/14 = -15/14
Now you have :
-3/7 / -15/14
When dividing by a fraction, flip the second fraction over and change divide to multiply:
-3/7 x -14/15
Now multiply top by top and bottom by bottom:
(-3 x -14) / ( 7 x 15) = 42/105
Simplify by diving each number by 21 to get the final answer :

Answer:
h = 2m
Step-by-step explanation:
Given that,
Length of pool, l = 20 m
Width of the pool, b = 36.8 m
The pool contains 1472 m³ of water.
We need to find how deep is the water in the pool.
The pool is in the shape of right rectangular prism. The volume of right rectangular prism is given by :
V = lbh
h is depth of water
[tex]h=\dfrac{V}{lb}\\\\h=\dfrac{1472}{20\times 36.8}\\\\h=2\ m[/tex]
Hence, water is 2 m deep in the pool.
Answer:
2 m

Answer:
Step-by-step explanation:
The slope of a line in the two-dimensional Cartesian coordinate plane is usually represented by the letter m m, and it is sometimes called underline {the rate of change} between two points. This is because it is the change in the y y -coordinates divided by the corresponding change in the x x -coordinates between two distinct points on the line.

Triangle MNL undergoes a dilation centered at the origin. The result is the green triangle. Which rule describes the dilation?
A. (x,y) ----> (5x,5y)
B. (x,y) ----> (3x, 3y)
C. (x,y) ----> (1/5x, 1/5y)
D. (x,y) ----> (-5x, -5y)
Answer:
A. (x,y) ----> (5x,5y)
The triangle's rule of dilation is (x,y) ——> (5x,5y). The right answer is A.
What is dilation?Dilation's mathematical definition. A change called dilation lets you resize an object. A technique for enlarging or constricting objects is dilation. This transformation produces an image that retains the original shape. The shape does, however, differ in size.
The coordinates of the points M and M' in the accompanying figure are (-10,10) and (-2,2), respectively.
The dilation will be calculated as:-
D = -10 / -2 = 5
Therefore, the dilation form will be,
(x,y) ----> (5x,5y).

A phone company charges you a monthly flat fee of $12 and $0.25 a minute per call. The bill for the month of September is $21. How many minutes were charged on this bill? a. Write an equation that models this situation using to represent the number of minutes b. Solve for and answer the question.
Answer:
36 minutes
Step-by-step explanation:
Flat fee = $12
Charges per minutes = $0.25
Total charges = $21
Total charges = flat fee + charges per minutes
21 = 12 + 0.25x
21 = 12 + 0.25x
21 - 12 = 0.25x
9 = 0.25x
x = 9 / 0.25
= 36
x = 36 minutes

Answer:
9:16
810
Step-by-step explanation:
Let's say the smaller rectangle has length 6 and width 3. Because they are similar with ratio 3:4, the larger rectangle has length 6 * 4/3 and width 3 * 4/3. In other words, length is 8 and width is 4.
Now compare areas:
smaller rectangle would have an area of 18 because length 6 * width 3 is area 18.
larger rectangle would have area 32 because length 8 * width 4 is area 32.
The ratio here is 18:32 which simplifies to 9:16.
If the larger rectangle has area 1440, then the smaller rectangle has area 1440 * 9/16 = 810.
