Which statement illustrates the commutative property of addition?
A. (8i + 4) + (-8i – 4) = 0
B. (8i)- (-8i)= 0
C. 8i + 4 = 4i + 8
D. 8i + 4 = 4 + 8i
Answer:D
Step-by-step explanation:its the same thing but the numbers are flipped, you get the same answer either way.
The statement that illustrates the commutative property of addition is
8i + 4 = 4 + 8i. The correct option is D.
What is the commutative property of addition?The commutative property of addition:
Let a and b are numbers.
a + b = b + a
The change in the position of two numbers in an addition operation does not change the sum.
The commutative property of addition:
Let a and b are numbers.
So, a + b = b + a.
LHS = 8i + 4
= 2 (4i+2)
= 2(2 + 4i)
= 4 + 8i
That means, 8i + 4 = 4 + 8i holds the commutative property of addition.
Therefore, the equation is 8i + 4 = 4 + 8i.

Solve for k, please!
2(k − 5) = 12
Answer:
k = 11
Step-by-step explanation:
Expand brackets

add 10 on both sides
2k = 22
divide both sides by 2
k = 11
1.8 divide by 0.72 explain
Answer:
0.40
Step-by-step explanation:
Change the divisor 1.8 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
7.2 ÷ 18 = 0.40
and therefore:
0.72 ÷ 1.8 = 0.40
Both calculated to 2 decimal places.

Answer:
1/12 lb
Step-by-step explanation:
2/3 x 1/8 = 2/24 = 1/12
Step-by-step explanation: 2/3 / 8/1 is actually multiplying the first number by the reciprocal of the second. So 2/3 x 1/8. That equals 0.08333... or 1/12.

The time a student sleeps per night has a distribution with mean 6.06 hours and a standard deviation of 0.55 hours. Find the probability that average sleeping time for a randomly selected sample of 35 students is more than 6.15 hours per night.
Answer:
The probability is 0.16602
Step-by-step explanation:
We start by calculating the z-score
We have this mathematically as;
z-score = (x-mean)/SD/√n
From the question,
we have x = 6.15
mean = 6.06 hours
standard deviation = 0.55 hours
n = 35
Substituting these values, we have
z-score = (6.15-6.06)/0.55/√35
z-score = 0.09/0.55/5.92
z-score = 0.97
So the probability we want to calculate is:
P ( z > 0.97)
we make use of the standard normal distribution table here
The value is; 0.16602
XLiV represents 64 true ya false
Answer:
False
Step-by-step explanation:
Given
[tex]XLIV = 64[/tex]
Required
True or False
The above numeral can be split as follows:
[tex]XLIV = XL + IV[/tex]
X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:
[tex]XL = -10 + 50[/tex]
[tex]XL = 40[/tex]
In Roman numerals;
[tex]IV = 4[/tex]
Substitute 40 for XL and 4 for IV.
[tex]XLIV = 40 + 4[/tex]
[tex]XLIV = 44[/tex]
Hence;
[tex]XLIV = 64[/tex] is false

Find the specified value.
(2x +5)
a. Using the figure to the right, find the value of x.
b. Using the figure to the right find the value of y.
Answer:
a. The value of x is [tex]38^{o}[/tex].
b. The value of y is [tex]25^{o}[/tex].
Step-by-step explanation:
a. Applying the vertically opposite principle,
(2x + 5) = (3x - 33)
2x + 5 = 3x - 33
33 + 5 = 3x - 2x
38 = x
⇒ x = [tex]38^{o}[/tex]
b. Sum of angles on a straight line = [tex]180^{o}[/tex]
So that,
(4y - 1) + (3x - 33) = [tex]180^{o}[/tex]
But,
( 3x - 33) = (3x38 - 33)
= 114 - 33
= [tex]81^{o}[/tex]
(4y - 1) + [tex]81^{o}[/tex] = [tex]180^{o}[/tex]
4y - 1 = [tex]180^{o}[/tex] - [tex]81^{o}[/tex]
= [tex]99^{o}[/tex]
4y = [tex]99^{o}[/tex] + 1
= [tex]100^{o}[/tex]
y = [tex]\frac{100}{4}[/tex]
= [tex]25^{o}[/tex]
y = [tex]25^{o}[/tex]
The value of x is [tex]38^{o}[/tex], and y is [tex]25^{o}[/tex].

Your answer Shadae has 2/4 of a pizza. Robin has 3/8 of a pizza. How much pizza do the girls have altogether? Your answer Samantha drank 1/5 of a gallon of water for breakfast. She drank 3/10 vater after her afternoon workout. How much water did she drink in a
Answer:
Part A. The girls have 7/8 pizza all together.
Part B. Samantha drank 5/10 or 1/2 water that day.
Step-by-step explanation:
Part A. The answer is 7/8 because 2/4 is the same thing as 4/8.
2/4 = 4/8
4/8 + 3/8 = 7/8.
So, for the first question the answer is 7/8.
Part B. The answer is 5/10 because 1/5 = 2/10
1/5 = 2/10
2/10 + 3/10 = 5/10

Answer: Choice A) If Amber and Jorge each sell 5 trees in one week, they will earn the same amount
The amount they earn is $200 each.
========================================================
Explanation:
Let's form the equation for the amount Amber earns.
She starts off at $150, and then we add on 10x dollars. The 10x is because she earns 10 dollars per tree, and we have x be the number of trees sold.
Overall we can say her equation is y = 150+10x
This is the same as y = 10x+150
----------
Since Jorge's equation is y = 25x + 75, we can apply substitution to solve for x
y = 10x+150
25x+75 = 10x+150 .... replace y with 25x+75
25x+75-10x = 150 ... subtract 10x from both sides
15x+75 = 150
15x = 150-75 ... subtract 75 from both sides
15x = 75
x = 75/15 .... divide both sides by 15
x = 5
If they sell 5 trees per week, then Amber and Jorge earns the same amount of money.
That amount earned is
Amber: y = 10x+150 = 10*5+150 = 50+150 = 200 dollars
Jorge: y = 25x+75 = 25*5+75 = 125+75 = 200 dollars
Both earn $200 per week from selling 5 trees for that week. This helps confirm we have the right answer.
