The expression is 2(n-6), and in these two operations are
multiplication and subtraction with two constants 2, and 6.
What is an arithmetic operation?Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them. Addition, subtraction, multiplication, and division are the four basic math operations.
We have:
Twice the difference between a number and six
Let's suppose the number is n, then the expression becomes:
= 2(n-6)
The true statements are:
The two operations are multiplication and subtraction.The constants are 2 and 6. The expression is written as 2(n – 6)Thus, the expression is 2(n-6), and in these two operations are
multiplication and subtraction with two constants 2, and 6.

An equation is shown.
4c + 2c = 4c + 11/2
What value of 2c makes the equation true?
Answer:
[tex]\huge\boxed{\bf\:c = \frac{11}{4}}[/tex]
Step-by-step explanation:
[tex]4c + 2c = 4c + \frac{11}{2}[/tex]
Cancel 4c on both the sides of the equation.
[tex]2c = \frac{11}{2}[/tex]
Bring the 2 in the denominator of 11/2 to the left hand side of the equation.

Answer:
3/4
Step-by-step explanation:
If Ty and his brothers share a pizza equally, then the pizza is split into four parts because there are four people sharing it. That means that each person has 1/4 of the pizza.
Since Ty has 3 brothers, they share 3/4 of the pizza since 1/4 * 3 = 3/4.
-2-0.5b+12=0.3b+6.2
Step-by-step explanation:
-2 -0.5b + 12 = 0.3b + 6.2
-2 + 12 - 6.2 = 0.3b + 0.5b
3.8 = 0.8b
b = 3.8/0.8
= 4.75
Answer:
4.75
Step-by-step explanation:
-2-0.5b + 12 = 0.3b + 6.2
Move all terms to the left:
-2-0.5b + 12 - (0.3b + 6.2) = 0
Add all the numbers together, and all the variables
-0.5b - (0.3b + 6.2) + 10 = 0
Get rid of parentheses
-0.5b - 0.3b - 6.2 + 10 = 0
Add all the numbers together, and all the variables
-0.8b + 3.8 = 0
Move all terms containing b to the left, all other terms to the right
-0.8b = -3.8
b= -3.8/-0.8
b= 4+0.6/0.8
b= 4.75

The mean of five numbers is 8. If one of the five numbers is removed, the mean becomes 9. What is the value of the number that was removed
Using the mean concept, it is found that the value of the number that was removed was of 4.
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
The mean of five numbers is 8, hence, the sum of the numbers is given by:
S = 5 x 8 = 40.
If one of the five numbers is removed, the mean becomes 9, hence, the sum of the four numbers is given by:
S = 4 x 9 = 36.
The difference is:
40 - 36 = 4.
Hence, the value of the number that was removed was of 4.

please help asap!! i don't really understand this
Answer:
17*12 area of triangle is base*height
Answer:
Use the formula for the area of a triangle:
A = BH x 1/2
Where 'B' represents the base, 'H' the height, and multiplying by 1/2 just means dividing the product of those two lengths by 2.
What we know:
Base = 12 feetHeight = 17 feetWhich is all we need to know, so plug these values into our formula;
A = BH x 1/2
A = 12(17) x 1/2
Now just solve:-
A = 204 x 1/2
A = 204/2
A = 102, the area of this triangle is 102 ft²!

The equation of a circle is shown. What is the radius? 22 + y2 - 10x + 8y + 16 = 0
Answer:
radius = 5
Step-by-step explanation:
Given
x² + y² - 10x + 8y + 16 = 0Using completing the square method
x² - 10x + 25 - 25 + y² + 8y + 16 (x + 5)² + (y + 4)² - 25 = 0(x + 5)² + (y + 4)² = 25Standard form for equation of a circle
(x - h)² + (y - k)² = r², where r is the radiusOn comparison to our equation in the question :
r² = 25radius = 5 [as distances cannot be -ve]Answer:
radius = 5
Step-by-step explanation:
Question[tex]x^2+y^2-10x+8y+16=0[/tex]
The equation of a circle is shown. What is the radius?
----------------------------------------------------------------------------------
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Given equation:
[tex]x^2+y^2-10x+8y+16=0[/tex]
Collect like terms:
[tex]\implies x^2-10x+y^2+8y+16=0[/tex]
Subtract 16 from both sides:
[tex]\implies x^2-10x+y^2+8y=-16[/tex]
Complete the square for both variables.
Add 25 to both sides for x. Add 16 to both sides for y.
[tex]\implies x^2-10x+25+y^2+8y+16=-16+25+16[/tex]
[tex]\implies (x^2-10x+25)+(y^2+8y+16)=25[/tex]
Factor the two variables:
[tex]\implies (x-5)^2+(y+4)^2=25[/tex]
Therefore:
