Answer:

x=0.4

Step-by-step explanation:

5x=2

Divide 5 on both sides of the equation.

The 5 should be canceled out by its self

And drop the x down, and you should have left

over the 2 divided by 5, which should give you

x=0.4

And 0.4 is already rounded so that should be your final answer.

-6/7,-3/7,0,3/7 .... create a formula that explains the arithmetic sequence

LenKa [72]

The formula that explain the arithmetic sequence is $a_{n}=\frac{3}{7}n-\frac{9}{7}$

Step-by-step explanation:

The formula of the nth term in an arithmetic sequence is

$a_{n}=a+(n-1)d$ , where

a is the first term
d is the common difference between the consecutive terms

∵ $\frac{-6}{7}$ , $\frac{-3}{7}$ , 0 , $\frac{3}{7}$ are some terms of an arithmetic sequence

∵ The difference between two consecutive terms = $\frac{-3}{7}$ - $\frac{-6}{7}$

∴ The difference between two consecutive terms = $\frac{-3}{7}$ + $\frac{6}{7}$ = $\frac{3}{7}$

∴ The common difference = $\frac{3}{7}$

∴ d = $\frac{3}{7}$

∵ The first term is $\frac{-6}{7}$

∴ a = $\frac{-6}{7}$

- Substitute a and d in the formula above

∴ $a_{n}=\frac{-6}{7}+(n-1)\frac{3}{7}$

- Simplify the right hand side

∴ $a_{n}=\frac{-6}{7}+\frac{3}{7}n-\frac{3}{7}$

- Add like terms

∴ $a_{n}=\frac{3}{7}n-\frac{9}{7}$

The formula that explain the arithmetic sequence is $a_{n}=\frac{3}{7}n-\frac{9}{7}$

Elena donates some money to charity whenever she earns money as a babysitter. What percent of her income does She donate?

Leni [432]

Answer:

10%

Step-by-step explanation:

The question is incomplete due to missing data

Say she earns $1000

And she donates $100

Hence the percentage of her earnings she donates is

=100/1000*100

=10000/1000

=10%

Hence the percentage is 10%
