Hey there!
3/4
= 3 ÷ 4
= 0.75
= 75%
Option A.
12/16
= 12 ÷ 2 / 16 ÷ 2
= 6 / 8
= 6 ÷ 8
= 0.75
= 75%
Thus, this statement is: TRUE
Option B.
6/8
= 6 ÷ 2 / 8 ÷ 2
= 3 / 4
= 3 ÷ 4
= 0.75
= 75%
Thus, this statement is: TRUE
Option C.
15/20
= 15 ÷ 5 / 20 ÷ 5
= 3 / 4
= 3 ÷ 4
= 0.75
= 75%
Thus, this statement is: TRUE
Option D.
20/28
= 20 ÷ 2 / 28 ÷ 2
= 10 / 14
= 10 ÷ 2 / 14 ÷ 2
= 5 / 7
= 0.714286
= 71.4286%
Thus, this statement is: FALSE
Option E.
24/32
= 24 ÷ 2 / 32 ÷ 2
= 12 / 16
= 12 ÷ 4 / 16 ÷ 4
= 3 / 4
= 3 ÷ 4
= 0.75
= 75%
Thus, this statement is: TRUE
Therefore, your answers are
• Option A. 12/16
• Option B. 6/8
• Option C. 15/20
• Option E. 24/32

Which equation is equivalent to 7(r + 4) - 3?
7*r+7*4*3
7*r*7*4-3
7*r+7*4-3
7*r+7*4
Answer: Choice C
7*r+7*4-3
=========================================================
Reason:
We use the distributive property to go from 7(r+4) to 7*r+7*4
Multiply the outer 7 by each term inside.
Then the -3 tags along without any changes to it
So we go from 7(r+4) - 3 to 7*r+7*4 - 3
This can be simplified further to 7r+25, but your teacher has chosen not to simplify at this time.

What fraction of the books had 200 or fewer pages?
Answer: 1/2
Step-by-step explanation:
I took the ixl and I put 1/3 but it was actually 1/2
The fraction of books which had 200 or fewer pages is given by A = 1/2
What is box plot?A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary.
A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.
It is used when showing the distribution of data points across a selected measure and if the box in a box plot is stretched in one direction or the other, then the data is skewed in that direction.
Given data ,
Isabelle kept track of the number of pages in each book she read last summer
Now , let the box plot be represented as A
Now , the first and third quartile along with the median is given below ;
So , the fraction of books which had 200 or fewer books is given by A = 1/2
Hence , the box plot is solved and the fraction is A = 1/2

Below is the graph of y equation y=-|x-2|+3. Use this graph to find all values of x given each statement.
a) -|x-2|+3>0
b) -|x-2|+3<0
c) -|x-2|+3=0
Thank you!
Answer:
Step-by-step explanation:
a) x<5 and x>−1
b)x<-1,x>5
c)x=5,x=-1
For the equation:
y=-|x-2|+3 values of x for below cases are :
a) -|x-2|+3>0 , x ∈ (-1 , 5)
b) -|x-2|+3<0 , x ∈ R - [-1 , 5] or x ∈ (-∞ , - 1) U ( 5 , ∞)
c)-|x-2|+3=0 , x ∈ {-1 , 5}
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Graph of the equation:
⇒ y = -|x-2| + 3
To Find: Values of x in below cases:
a) -|x-2|+3>0
b) -|x-2|+3<0
c)-|x-2|+3=0
Solution:
a) -|x-2|+3>0
y=-|x-2|+3
⇒ y > 0
Hence, From the graph y > 0 when x ∈ (-1 , 5)
without using graph :
- |x - 2| + 3 > 0
3 > | x - 2|
| x - 2 | < 3
Case 1 : x - 2 > 0
x - 2 < 3
x < 5
Case2 : x - 2 < 0
x - 2 > - 3
x > - 1
b) -|x-2|+3<0
y=-|x-2|+3
y < 0
From the graph y > 0 when x < - 1 or x > 5
x ∈ R - [-1 , 5]
or, x ∈ (-∞ , - 1) U ( 5 , ∞)
without using graph :
-|x-2|+3<0
3 < | x - 2|
| x - 2 | > 3
case 1 : x - 2 > 0
x - 2 > 3
x > 5
case 2 : x - 2 < 0
x - 2 < - 3
x < - 1
a) -|x-2|+3=0
y=-|x-2|+3
y = 0
From the graph y = 0 when x = -1 and 5
x ∈ {-1 , 5}
without using graph :
-|x-2|+3=0
3 = | x - 2|
| x - 2 | = 3
case 1 : x - 2 = 3
x = 5
case 2 : x - 2 = - 3
x = - 1
Thus, For the equation: y=-|x-2|+3 values of x for below cases are :
a) -|x-2|+3>0 , x ∈ (-1 , 5)
b) -|x-2|+3<0 , x ∈ R - [-1 , 5] or x ∈ (-∞ , - 1) U ( 5 , ∞)
c)-|x-2|+3=0 , x ∈ {-1 , 5}

Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we have that:
The rate in Brazil is of [tex]5 \times 10^4[/tex].The rate in the United States is of [tex]14000 = 1.4 \times 10^4[/tex].Hence, the rate between the consumption in Brazil and in the United States is given by:

Step-by-step explanation:
Area of Rectangle: Area = Length * Width
Given information:
Area = 22 in^2Length = 2x - 1Width = x - 4Put that into the Formula.
Area = Length * Width
22 in^2 = (2x - 1) * (x - 4)
Solve.
22 in^2 = (2x - 1) * (x - 4)
[tex]22 = (2x^2 - 9x + 4)\\2x^2 - 9x - 18 = 0[/tex]
Factor it.
(2x^2 - 9x - 18) = 0
(2x + 3)(x-6) = 0
[tex]x=-\frac{3}{2} ,6[/tex]
Plug that into the Length and Width to find the actually Length and Width.
Length:

The value of y is directly proportional to the value of x. If y = 45 when x = 140, what is the value of y when x = 70?
Step-by-step explanation:
Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX
"K" is the constant of proportionality and must be determined from the initial information.
If Y = 45 when X=140 means 45 = 140K
K = 45/140 = 0.32
Now that we know the value of K, we can use it to calculate the value of Y when X=70
Y = (0.32)(70) = 22.4
