Answer:

x = - 4

Step-by-step explanation:

Given

2(x - 8) = x + 5x ← distribute left side and simplify right side

2x - 16 = 6x ( subtract 6x from both sides )

- 4x - 16 = 0 ( add 16 to both sides )

- 4x = 16 ( divide both sides by - 4 )

x = - 4

Find P 20 of the following arithmetic sequence: 206, 212, 218, 224....

Yanka [14]

Answer:

$p_{20} = 1.25528$

P₀ = 206 and difference d = 6

Step-by-step explanation:

Step(i):-

Given that the arithmetic sequence

206,212,218,224,.....

P₀ = 206 and difference d = 212-206 = 6

The $n^{th}$ term of the sequence

$t_{n} = ar^{n-1}$

Step(ii):-

The $n^{th}$ term of the sequence

$P_{n} = ar^{n-1}$

Put n=20

$P_{20} = 206 ( 6) ^{20-1}$

$p_{20} = 1.25528$

Simplify the expression.

Tamiku [17]

Answer:

$\boxed{=144--> C.}$

Step-by-step explanation:

You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract that came from left to right.

First you calculate with parenthesis first.

$(13-1)^2/2$

$12^2/2$

Then you calculate with exponents.

$12^2=12*12=144$

$144/2$

Next, divide from left to right.

$144/2=72$

$144/72=2$

$72*2=144$

$2*72=144$

$=72$

$2*72$

Finally, multiply from left to right.

$72*2=144$

$12*12=144$

Final answer: $\boxed{=144}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

George charged a motorized bicycle on his credit card for $2,000 on June 12. His balance before that purchase on that credit car

Gnesinka [82]

The calculation uses the accumulated daily balance method (ADB).
We assume the statement is based on calendar month (rare!).

George owes $500 from beginning to end of June, so 30 days out of 30.
Interest accrued is 500*0.013*30/30=$6.50.
He also owes $2000 from June 12 to June 30, so 19 days inclusively.
Interest accrued is $2000*.013*(19/30)=16.47
Total interest at the end of the month=$6.50+$16.47=$22.97
