Why do you first combine like terms and then use Distributive Property to solve 8(5x+9x+6)=160?

You can actually do it either way, you could distribute first and then combine, you would get the same answer. I guess it just depends on what you find easier. Here is how to solve it both ways:

Combining First:

8(5x+9x+6)=160

8(14x+6)=160

112x+48=160

112x=112

x=1

NOT Combining First:

8(5x+9x+6)=160

40x+72x+48=160

112x+48=160

112x=112

x=1

so, you would get the same answer both ways, it is of personal preference what you do first.

the sum of the first n terms of a sequence is 20 - 10 / 2 ^ n - 1 find the sum of the first five terms​
Travka [436]

Answer:

S_5=\dfrac{170}{9}

Step-by-step explanation:

Given that,

The sum of first n term of a sequence isS_n=20-\dfrac{10}{2n-1}

We need to find the sum of the first 5 terms.

Put n = 5,

S_5=20-\dfrac{10}{2(5)-1}\\\\=20-\dfrac{10}{10-1}\\\\=20-\dfrac{10}{9}\\\\=\dfrac{170}{9}

So, the sum of first 5 terms is equal to \dfrac{170}{9}.
