If you triple 4 and subtract 2 each day how many days until you have zero
Answers
4 x 3 = 12
12 - 2 x 6 = 0
It takes 3 days until the value becomes zero when you triple 4 and subtract 2 each day.
Let "d" be the number of days, and "x" be the value at the end of each day.
On the first day, "x" starts at 4, and then it's reduced by 2 each day. So, the value at the end of each day can be represented as:
Day 1: x = 4
Day 2: x = 4 - 2 = 2
Day 3: x = 2 - 2 = 0
As we can see, on Day 3, the value becomes zero.
Therefore, it takes 3 days until the value becomes zero when you triple 4 and subtract 2 each day.

Step-by-step explanation:
1) Below the number line, rewrite all of the several numbers as improper fractions, a fraction whose numerator is greater than the denominator on a number line. In this case, let's restrict ourselves to the numbers greater than 1.

2) Generally, Mixed Numbers represent not exact divisions so they must be between whole numbers line.
To Convert an Improper fraction into a Mixed Number:
Keep the denominator.
Divide the Numerator by the Denominator, placing the remainder as the new Numerator and the quotient as the whole number.
3) We could have other improper fractions and their Mixed Numbers.

Step-by-step explanation:
8 + (12) = 20
Answer:
20.
Step-by-step explanation:
To find the value of "n" in the equation 8 + n = 20, we can use the concept of solving for an unknown variable.
To isolate "n" on one side of the equation, we can subtract 8 from both sides:
8 + n - 8 = 20 - 8
This simplifies to:
n = 12
Therefore, the value of "n" in the equation 8 + n = 20 is 12.
In this equation, the value of "n" is 12 because when we add 8 to it, the result is 20.

Solve by factoring
Answers
Answer:
see explanation
Step-by-step explanation:
(13)
v² - 11v + 18 = 0 ← in standard form
(v - 2)(v - 9) = 0 ← in factored form
Equate each factor to zero and solve for v
v - 2 = 0 ⇒ v = 2
v - 9 = 0 ⇒ v = 9
solutions are v = 2, v = 9

5x² - 12x + 7 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × 7 = 35 and sum = - 12
The factors are - 5 and - 7
Use these factors to split the x- term
5x² - 5x - 7x + 7 = 0 ( factor the first/second and third/fourth terms )
5x(x - 1) - 7(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(5x - 7) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
5x - 7 = 0 ⇒ 5x = 7 ⇒ x =
solutions are x = 1, x =
