The distance from the Sun to Mars is an average of 2.1 repeating. 1 times the distance from the Sun to Venus. How can this repeating decimal be expressed as a fraction?

19/9

Step-by-step explanation:

We are given repeating decimal number 2.1¯.

We know 2.1¯ = 2.1111 repeating 1's.

Let us assume x is a fraction equals given repating decimal number.

And set it as a first eqaution.

x =  2.1111             (equation 1).

Multiplying equation both side by 10 ( because only one digit is repeating after decimal, we multiply by 10).

On multiplying by 10 we get

10*x = 10*2.1111  

10x = 21.1111             (equation 2)

Subtracting equation 1 from equation 2, we get

10x = 21.1111

-x =  -2.1111

9x = 19.

Now, dividing both sides by 9. we get

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
