If the common difference in an arithmetic sequence is 4, and the 20th term is 36, what is the first term?

Answers

The sum of an arithmetic sequence can be found using the formula S = n/2(a + l) where S equals sum, n equals # terms, a equals the first term and l equals last term we know enough of these to find the missing pieces S = -15n = 20a = 4 -15 = 20/2 (4 + l) now we only have one unknown -15 = 10 (4 + l)-15 = 40 + 10l-55 = 10l l = -5.5 so the last term is -5.5 now we can use anothe formula to find the common difference l = a + (n-1) d so the last term equals the first term (a) plus # terms -1 times (d) the common difference -5.5 = 4 + (20-1) d -9.5 = 19 d d = -.5 so your common difference is -.5

A = v/t. Solve for t

Answers

A = v/t Multiply both sides by t
A(t) = v Divide both sides by A
t = v / A

The original price of an electric scooter was $187.50. The scooter was on sale for $165. What was the discount rate?

Answers

so the origiinal price is 187.50 and the sale price was 165, so the discount is 187.50 - 165 = 22.5.

if we take 187.50 to be the 100%, what is 22.5 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\n \cline{1-2} 187.5&100\n 22.5&x \end{array}\implies \cfrac{187.5}{22.5}=\cfrac{100}{x}\implies 187.5x=2250 \n\n\n x=\cfrac{2250}{187.5}\implies x=12$

Answer: I got 12% after trial an error from 15% down to 12% when i got 165$

Solve the following equation. Then determine if the equation is an identity or a contradiction.2(3n + 3) - 9 = 6n

Answers

Let's solve the equation step by step:

1. Start with the equation: $2(3n+3)-9=6n$.

2. First, distribute the 2 on the left side of the equation:
$6n + 6 - 9 = 6n$.

3. Next, simplify the equation by combining like terms. The 6n on both sides can be canceled out:
$6 - 9 = 0$.

4. Simplify further:
$-3 = 0$.

Now, let's analyze the result:

The equation $-3 = 0$ is a contradiction. This means that there is no value of $n$ that will satisfy the equation. In other words, there is no solution to this equation.
