Answer:

Step-by-step explanation:

Each term is half the one before it, so the eighth term is 1/2^7 * 8 or 1/16. So 1/16 can be written as 0.0625 or D.

bryan has some 3 cent stamps and some 4 cent stamps. what is the least number of stamps he can combine so the value of the stamp

SashulF [63]

Answer:

The least number of stamps required is $9$

Step-by-step explanation:

Let the number of $3$ cent stamps be $x$ and $4$ cent stamps be $y$

We have

$3x+4y=33$

The minimum number is obtained when more $4$ cent stamps are used

Here $y$ cannot be greater than $8$ since $\frac{33}{4}$

Substitute $y=8$

$3x+4\times 8=33\\\\3x=1\\\\x=\frac{1}{3}$

Not possible since $x$ is not a fraction

Substitute $y=7$

$3x+4\times 7=33\\\\3x=5\\\\x=\frac{5}{3}$

Not possible since $x$ is not a fraction

Substitute $y=6$

$3x+4\times 6=33\\\\3x=9\\\\x=\frac{9}{3}\\\\=3$

Possible

Hence minimum number of stamps is

$=x+y\\\\=3+6\\\\=9$

Find the sum 7a/a+5 + a/a-2

IRINA_888 [86]

$\dfrac{7a}{a+5}+\dfrac{a}{a-2} \\\dfrac{7a(a-2)+a(a+5)}{(a+5)(a-2)} \\\boxed{\dfrac{a(8a-9)}{(a+5)(a-2)}}$

Hope this helps.
