Tim sold half of his comics collection and then bought 16 more. If he now has 36, how many did he begin with?

STALIN [3.7K]

Tim began with 40 comics

Further explanation:

The equation involve linear equation as there is only one object i.e. comic books

So,

Let x be the number of comic books Tim began with

Then after selling half comics Tim will have x/2 comics remaining

Now when he buys 16 more the expression will be:

$\frac{x}{2}+16$

He has total 36 books, then

$\frac{x}{2}+16= 36$

Subtracting 16 from both sides

$\frac{x}{2}+16-16= 36-16$

${\frac{x}{2}}= 20\\$

Multiplying 2 on both sides

${\frac{x}{2}}* 2= 20*2\\x=40$

<u>We can recheck, if he had 40, half of them will be 20 and adding 16 makes them 36.</u>

The height of sunflowers can be represented by a geometric sequence. The first measurement showed the sunflowers to be 12 inches

Vika [28.1K]

The first term is 12.

The second term is 12r, where r is the common ratio. We multiply any term by the common ratio to get the next term.

The third term is (12r)*r = 12r^2.

The fourth term is (12r^2)*r = 12r^3

The fifth term is (12r^3)*r = 12r^4. The fifth term is also 20.27 which was given to us.

Equate the two items and solve for r.

12r^4 = 20.27

r^4 = 20.27/12

r = (20.27/12)^(1/4)

r = 1.14003484493186 which is approximate

-----------------------

We can now find the approximate terms of this sequence

a = first term

a = 12

b = second term

b = a*r

b = 12*1.14003484493186

b = 13.6804181391823

c = third term

c = b*r

c = 13.6804181391823*1.14003484493186

c = 15.5961533719058

d = fourth term

d = c*r

d = 15.5961533719058*1.14003484493186

d = 17.7801582908741

e = fifth term

e = 17.7801582908741*1.14003484493186

e = 20.2700000000006

The 6 at the end is due to rounding error.

Therefore, the sequence has these five terms in the exact order shown

12
13.6804181391823
15.5961533719058
17.7801582908741
20.27

The sequence notation of this function is

{12, 13.6804181391823, 15.5961533719058, 17.7801582908741, 20.27}

Round those values however you need to.
