Use any order, any grouping to write an equivalent expression: 3(2x) + 4y(5) + (4 x 2 x z)
Answer:
We conclude that the equivalent expression is:
[tex]3\left(2x\right)+4y\left(5\right)+\left(4\times \:2z\right)=6x+20y+8z[/tex]
Step-by-step explanation:
Given the expression
[tex]3\left(2x\right)+4y\left(5\right)+\left(4\times \:2z\right)[/tex]
Remove parentheses: (a) = a
[tex]=3\times \:2x+4\times \:5y+4\times \:2z[/tex]
Multiply the numbers: 3 × 2 = 6
[tex]=6x+4\times \:5y+4\times \:2z[/tex]
Multiply the numbers: 4 × 5 = 20
[tex]=6x+20y+4\times \:2z[/tex]
Multiply the numbers: 4 × 2 = 8
[tex]=6x+20y+8z[/tex]
Thus, we conclude that the equivalent expression is:
[tex]3\left(2x\right)+4y\left(5\right)+\left(4\times \:2z\right)=6x+20y+8z[/tex]

What is the closure property of multiplication for rational
expressions? Explain why rational expressions are
closed under multiplication.
Answer:
The closure property states that for any two rational numbers a and b, a × b is also a rational number. The result is a rational number. So rational numbers are closed under multiplication.
Step-by-step explanation:

Closure property under multiplication states that any two rational numbers' product will be a rational number.
What is the closure property of multiplication?Closure property states that when a set of numbers is closed under any arithmetic operation such as addition, subtraction, multiplication, and division and is performed on any two numbers of the set with the answer being another number from the set itself. This property is applicable for real numbers, whole numbers, integers, and rational numbers.
Closure property under multiplication states that any two rational numbers' product will be a rational number, i.e. if a and b are any two rational numbers, ab will also be a rational number.
Example: 2/3 × 3/5 = 2/5
Here, 2/3 and 3/5 are rational numbers, so 2/5 also rational number.
Therefore, closure property under multiplication states that any two rational numbers' product will be a rational number.

Antonio orders an iPhone case off of Amazon for $27. He has to pay an additional 3% for shipping and handling. How much will his total bill be?
Answer:
We conclude that total cost/bill will be: $27.81
Step-by-step explanation:
Given
The cost of an iPhone case = $27
Additional expense = 3% = 3/100 = 0.03
To determine
Total bill = ?
The expense amount can be calculated by multiplying the cost of an iPhone case by the additional expense
i.e.
Expense Amount = cost of an iPhone case × additional expense
= 27 × 0.03
= $0.81
The total cost is calculated by adding the expense amount and the original cost of an iPhone case.
i.e.
Total cost/bill = Expense Amount + cost of an iPhone case
= $0.81 + $27
= $27.81
Therefore, we conclude that total cost/bill will be: $27.81

Answer:
9 is the correct answer all the best
Step-by-step explanation:
(x + 0.5)/6 = 19/12
2(x + 0.5) = 19 (multiply 12 on both sides)
x + 0.5 = 9.5 (divide 2 on both sides)
x = 9 (subtract 0.5 on both sides)
The answer is 9.

Jaquan practices soccer every three days. He practices basketball every five days Jaquan practiced both today. How many days until he practices both
Answer: He will practice both on every 15 days.
Step-by-step explanation:
Given: Jaquan practices soccer every 3 days.
He practices basketball every 5 days Jaquan practiced both today.
The number of days until he practices both = Least common multiple of 3 and 5
= 3 x 5 [Both are primes]
= 15
Hence, he will practice both on every 15 days.
Least common multiple of two numbers p and q is the smallest number that is divisible by both p and q.

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch =1578x 10-5 miles
Answer: (7.129)*10^(7) inches.
Step-by-step explanation:
We know that:
1 inch = 1.578*10^(-5) miles.
If we divide both sides by 1.578*10^(-5), we get:
(1/1.578*10^(-5)) inches = 1 mile
63,371.36 inches = 1 mile
Now, we have 1,225 miles, this is equal to 1,125 times 63,371.36 inches
Then 1,225 miles writen in inches is:
1,125*(63,371.36 inches) = 71,292,780 inches.
Now, to write this in scientific notation, we need to count the number of decimals between the first one at the left, and the decimal point.
In this case we have 7 decimals.
Now, let's take the first 4 decimals, (7129) and write a decimal point after the first one:
(7.129)
Now let's multiply this by then to the power of 7 (where 7 is the number of decimals we found above).
Then the scientific notation of 71,292,780 inches. is:
(7.129)*10^(7) inches.

Hey Guys, I was wondering if you could help What are the constants in this expression: 6x-8+4y+5 out of these choices: 6, 4 6x, -8, 4y, 5 8, 5 6, -8, 4, 5 -8, 5
Given:
The expression is
[tex]6x-8+4y+5[/tex]
To find:
The constants in the given expression.
Solution:
Terms can be a number, variable and product of both. these are separated by "+" sign.
Variables terms: These terms contains at least one variable.
Constant terms: These terms are free from the variables. it means there are no variable.
We have,
[tex]6x-8+4y+5[/tex]
In this expression, the terms are 6x, -8, 4y, 5, variable terms are 6x, 4y and constant terms are -8, 5.
Therefore, the last option is correct, i.e., -8, 5.
Can a triangle with side lengths of 15, 13, and 6 can be classified as a right triangle? ? and why?
Answer:
The triangle cannot be classified as right angled triangle.
Step-by-step explanation:
Given measurements are;
15, 13 and 6.
In right angle triangle, the sum of square of lengths of smaller sides is equal to square length of larger side.
Therefore,
[tex](6)^2 + (13)^2 = (15)^2\\36 + 169 = 225\\205 \neq 225[/tex]
Hence,
The triangle cannot be classified as right angled triangle.
