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]

Answer:

Read lol.

Step-by-step explanation:

Ok for example with the graph below. You want to find the slope. The slope of this graph is 4/5, because I did the technique rise over run. You want to find a point on the line that is in the middle of a square and then find another point and measure. Go up until it meets the other and then go left or right depending on the direction of the line.

After you find the slope you want to find the y-intercept. To find the y-intercept take any point on the line and plug it into this formula with the slope: y=mx+b

So I took the point (0,3): 3=(4/5)(0)+b

Solve:                               3=0+b

                                        3=b

And then wen u have all the right material for your equation, you can plug it all in, which gets me: y=4/5x+3

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.

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.

Answer:

20x > 33 = 2

Step-by-step explanation:

divide 20x by 20 do the same with 33

20x/20 > 33/20

x > 1.65

1 isnt a prime number and the closest prime number to 1.65 is 2

the answer is x > 2

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.

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:

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:

brainliest plzzzzzz

Closure property under multiplication states that any two rational numbers' product will be a rational number.

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.

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.

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.
