twelve less than four times some number n is at least three more than the number. What values are possible for n?

Answers

Answer 1

Answer: 4n -12 >n
4n > n + 12
3n > 12
n > 4
So 5,6,7,8,9, and so on

Answer 2

Answer:

Answer:

10.

n/2 +12 - 4

4/2 + 12 - 4

2 + 8

If 15 is the fifth number in a series of five consecutive odd numbers what is the third number in the series ?What is the answer is 11 or 9 ?? I think it's 11. What is yr answer ??

Answers

It doesn't matter how many there are altogether.

All you need to know is that 15 is the fifth odd number,
and you need the third odd number.

So the one you want is 2 odd numbers back from 15. That's 11 .

$15 - 5th\n 13 - 4th\n \boxed{11} - 3rd$

Four times a number, x, plus five times a number, y, equals 79. Ten times x minus 5 times y equals 5. Find the numbers by setting up a system of linear equations and solving the system using the elimination method.a) x = 7, y = 9
b) x = 6, y = 11
c) x = 8, y = 10
d) x = -10, y = 7

Answers

the correct answer is X=6 & Y=11

2. If a circle has the diameter of 8, what is the circumference?

Answers

Since diameter is 8 the circumference is 8 pi

3.14 is the circumference and the diameter is 8 ,diameter is half of a radius so you have to do 3.14 times 16 and that's you circumference
answer:50.24

If the equation of a circle is (x + 4)2 + (y - 6)2 = 25, its radius is:

Answers

Hey there :)

The equation of a circle is:
( x - h )² + ( y - k )² = radius²

Therefore, in this example,
( x + 4 )² + ( y - 6 )² = 25
25 = radius²
$√(radius^2) = √(25)$
radius = 5

Final answer:

The equation you provided is a standard form equation for a circle. By comparing it to the general circle equation and taking square root of the constant on the right side, we find that the radius of the circle is 5.

Explanation:

The equation of a circle is typically given in the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius.

Looking at your given equation: (x + 4)² + (y - 6)² = 25, we can see that this fits the general form.
The radius r is given by the square root of the number on the right side of the equation. In this case, it equals to √25 which is 5.

Therefore, the radius of the circle is 5.

What represents the equal number of parts that equal a whole in a fraction.

Answers

This refers to the "denominator" of a fraction. By definition, the denominator tells you how many you need to have of an equal part in order to create a whole. The numerator tells you how much of those equal parts you have.
