Answer:

Step-by-step explanation:

The bar above the 3 in the 2.3 means that the 3 repeats indefinitely and the number is really 2.333333...which can also be 2 1/3 since 0.33333 = 1/3.

3 2/3 + 2 1/3

1/3 and 2/3 make 1

3 and 2 make 5

1 + 5 = 6

Adding together we get 6, so that is your answer.

I'm always happy to help :)

Answer:

Step-by-step explanation:

The overbar means the digit repeats indefinitely. The repeating decimal 0.333... is equivalent to 1/3, so this is the simple addition ...

3 2/3 + 2 1/3 = 5 3/3 = 6

<em>Comment on the repeating decimal</em>

1/3 = 0.3333... repeating is one of the first decimal equivalents you learn.

If you're into repeating decimals. you may have learned how to convert them to fractions:

x = 0.3333... repeating . . . . . . . give a name to the value

10x = 3.3333... repeating . . . . . multiply by 10^p where p is the number of digits in the repeating pattern

10x - x = 3.3333... - 0.3333... = 3 . . . . . subtract: the repeating portions cancel

9x = 3 . . . . . . . . . .simplify

x = 3/9 = 1/3 . . . . .divide by the x-coefficient; simplify

Madison and her sister received the same amount of money to go out to eat. each girl spent $13. after lunch, the girls had a tot

Rus_ich [418]

Each girl started with 15 dollars.

4$ is the ending amount
x= the amount of money each girl received
4= 2x - 2(13)

Since there were two girls who both received x amount of money, x is multiplied by two. Since both the girls spent 13 dolars on lunch, their original amount is subtracted by 13 times two, since there are two lunches being bought. The end amount of money is four.
to solve:
4= 2x - 2(13)
4= 2x - 26       Simplify by combining like terms
30= 2x             Isolate the variable by adding 26 to both sides
15=x                Continue to isolate the variable by dividing both sides by two
Each girl started with 15 dolars. Each girl spent thirteen dolars on lunch and had two dolars left over. Each girls' two dolars left over adds up to four dollars.
