How do you find the answer to 3x+2.5=6.1

Y_Kistochka [10]

You would get rid of the 2.5 by subtracting 2.5 on both sides, then the equation becomes
3x=3.6
solve for X by dividing 3 on both sides

What is the value of a? 9

Vera_Pavlovna [14]

ΔBED and Δ DEC are similar (AAA). Therefore we have the proportion:

$\dfrac{a}{18}=\dfrac{4}{a}$ cross multiply

$a^2=(18)(4)\\\\a^2=72\to a=\sqrt{72}\\\\a=\sqrt{36\cdot2}\\\\a=\sqrt{36}\cdot\sqrt2\\\\\boxed{a=6\sqrt2}$

Janelle invests in a piece of art that cost 600 British Pounds. A study found that art appreciates in value at a rate of 3.97% p

Pavel [41]

Answer:

It will be worth about £885.59.

Step-by-step explanation:

The art piece originally costs £600.

And it appreciates at a rate of 3.97% each year.

And we want to find the value of the art after 10 years.

We can write an exponential function to model the situation. The standard exponential function is given by:

$f(t)=a(r)^t$

Where t is the time in years.

Since it appreciates at a rate of 3.97% each year, the value after each year will be (100% + 3.97%) or 103.97%.

103.97% = 1.0397. So, r = 1.0397:

$f(t)=a(1.0397)^t$

Our a is the initial value. Therefore:

$f(t)=600(1.0397)^t$

Then the value of the piece of art after 10 years is:

$f(t)=600(1.0397)^{10}=885.5879...\approx \pounds 885.59$

It will be worth about £885.59 after 10 years.

Given the sequence 4,10,16,22,28, is 576 a member of this sequence

zhannawk [14.2K]

Hints:

1) This is an arithmetic sequence.
2) The first member of the sequence is 4.
3) The common difference is 6. To each member, we add 6 to get the next.
4) The formula for the nth term of an arith. sequence is as follows:

l=a + (n-1)d, where l is the LAST term, n is the number of terms, d is the common difference, and a is the first term. Write this out. Play with n, increasing (integer) n until this formula predicts numbers close to 576. Do you get exactly 576 for one of these INTEGER n values? If yes, then 576 is a member of the sequence. If no, then it is not.
