Well, if we use the Associative Property, we can switch around the positions of the 11, which is out of the parentheses. So, what we do is we put 11 and 3 into parentheses and r out of the parentheses, which makes:
r + (11 + 3)
So, now we solve the parentheses:
r + (14)
And finally, remove the parentheses. So, therefore, the answer is r + 14.

The perimeter of a rectangle a picture frame is 66 inches. the length is 3 inches greater than the width the system of linear equations used to represent the situation shown below.
2X + 2Y = 66 and X +3 =Y
solve the system name dimension represented by each variable
Given:
The perimeter of a rectangular picture frame is 66 inches [2X + 2Y = 66.]The length of the frame is 3 inches greater than the width [X + 3 = Y.]To find: The dimensions.
Answer:
Formula to find the perimeter of a rectangle = 2 × (Length + Width)
We know that 2X + 2Y = 66. Simplifying it, we get:
2(X + Y) = 66
X + Y = 66/2
X + Y = 33
Now that we know the value of X + Y, and assuming X and Y to be the dimensions, let's substitute it into the formula to find the perimeter and verify it.
Perimeter = 2 × (X + Y)
66 = 2 × 33
It's verified.
Now, we also have the expression representing the length, which is X + 3 = Y.
X + Y = 33
X + 3 = Y
Let's add both expressions.
X + Y + X + 3 = 33 + Y
2X + Y + 3 = 33 + Y
2X = 33 - 3 + Y - Y
2X = 30
X = 30/2
X = 15
Hence, the width [X] is 15.
Substituting this value into the expression representing the length,
15 + 3 = Y
18 = Y
Hence, the length and breadth of the rectangular picture frame is 18 and 15 units respectively.
Hope it helps. :)
A large corporation gave an assessment to its candidates for supervisory positions. The candidates were sorted into successful and unsuccessful groups based on whether they passed the assessment. The data is summarized in the table shown.

128
214
300
Answer:
214.
Step-by-step explanation:
According to the table, The number of people that were successful (The row that follows the word "Successful") and not selected (The Column that follows the words "Not selected") were 214 of the candidates.
To find the answer to this question, you have to find where the Row labeled "Successful" and Column labeled "Not Selected" intersect.

The function f is defined by the following rule f(x) = 5x -5 Complete the function table. -5 -1 I 2 3 4
Answer:
x f(x)
-5 -30
-1 -10
2 5
3 10
4 15
Step-by-step explanation:
Let us solve the question
∵ The function f is defined by the rule f(x) = 5x - 5
∵ x = -5
→ Substitute x in f by -5 to find the value of f(-5)
∴ f(-5) = 5(-5) - 5 = -25 - 5 = -30
∴ f(-5) = -30
∵ x = -1
→ Substitute x in f by -1 to find the value of f(-1)
∴ f(-1) = 5(-1) - 5 = -5 - 5 = -10
∴ f(-1) = -10
∵ x = 2
→ Substitute x in f by 2 to find the value of f(2)
∴ f(2) = 5(2) - 5 = 10 - 5 = 5
∴ f(2) = 5
∵ x = 3
→ Substitute x in f by 3 to find the value of f(3)
∴ f(3) = 5(3) - 5 = 15 - 5 = 10
∴ f(3) = 10
∵ x = 4
→ Substitute x in f by 4 to find the value of f(4)
∴ f(4) = 5(4) - 5 = 20 - 5 = 15
∴ f(4) = 15
Find the equation of the line through (-1, 3) and (5,3)
Given:
A line passes through (-1, 3) and (5,3).
To find:
The equation of the line.
Solution:
The line passes through (-1, 3) and (5,3). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{3-3}{5-(-1)}(x-(-1))[/tex]
[tex]y-3=\dfrac{0}{5+1}(x+1)[/tex]
[tex]y-3=0[/tex]
Adding 3 on both sides, we get
[tex]y-3+3=0+3[/tex]
[tex]y=3[/tex]
Therefore, the equation of the line is [tex]y=3[/tex].

the duration of a flash from a camera is timed at 0.004 seconds accurate to 1 / 1000 of a second calculate the upper and lower bounds for the duration of the flash using in quality
Answer:
0.0035 ≤ x ≤ 0.0045
Step-by-step explanation:
Given that:
The error = 1/1000 = 0.001 / 2 = 0.0005 s
Hence, 0.004 ± Error
0.004 ± 0.0005
Lower boundary = (0.004 - 0.001) = 0.0035
Upper boundary = (0.004 + 0.001) = 0.0045
0.0035 ≤ x ≤ 0.0045
