Answer:

Tn=a+(n−1)d, where a= First term, d= Difference between terms ... (2)

Equating (1) and (2)

6n+5=a+(n−1)d

6n+5=a+nd−d ..... (3)

Equating n terms:6n=nd

d=6 ...... (4)

Substituting (4) in (3)

6n+5=a+6n−6

5=a−6

a=11 ..... (5)

Now

Sn=2n(2a+(n−1)d)

Sn=2n(a+Tn) ....... (6)

Substituting (1) and (5) in (6)

Sn=2n(11+6n+5) 

Sn=2n(16+6n) 

Sn=n(8+3n)

Solve 2(1 – x) > 2x.
x < 2
x < 0.5
x > 0.5
x > 2

Answers

Answer:

x<0.5

Step-by-step explanation:

Hello lzukuXKachan!

[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]

Solve 2(1 – x) > 2x.

x < 2

x < 0.5

x > 0.5

x > 2

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex]2 ( 1 - x ) \gt 2 x[/tex]

Firstly, cancel out 2 from both sides of the equation. Now, the equation will be....

[tex]1 - x > x[/tex]

Now, subtract x from both sides.

[tex]1 - x - x > 0[/tex]

Combine -x & -x. It'll be one -2x.

[tex]1-2x>0 [/tex]

Again subtract 1 from both the sides. Remember :- any number subtracted from 0 will result in its negation

So, it'll be -1.

[tex]-2x>-1 [/tex]

Divide both sides by -2.

[tex]x<\frac{-1}{-2} \\ [/tex]

Remove the negative signs. (negative ÷ negative = positive)

[tex]x<\frac{1}{2} \\ = \large\boxed{ \boxed{ \bf \: x < 0.5}}[/tex]

Step-by-step explanation:

There are 4 A's and 3 B's, so the ratio would be 4:3.

The ratio would not be 3:4, because you are asking for A's to B's, and not B's to A's.

Answer:

4:3

Step-by-step explanation:

There are 4 A's in this set and only 3 B's. Often confused as 3:4, however, that would be the ratio of B's to A's. This ration can't be simplified either leaving it at 4:3.
