PLEASEEE ANSWERR
in which pair do both decimals represent rational numbers?

C. 0.752 and 0.232323...

Step-by-step explanation:

Rational number is a group of numbers that can be written as a ratio of two integers. Basically that means that rational numbers can also be written as fractions.

Speaking of decimals, decimal numbers can be rational if they have finite number of decimals (0.752). Ecception to this rule are repeating decimals numbers; decimal numbers which have infinitely many decimals but they repeat in a pattern (0.23232323...).

Now, knowing this, it's easy to answer the question.

I hope this helped.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
