How to find where the equations meet.
zzz [600]
The first sentence → x - 2y = -1
the second one → 3x - 2y = -3

multiply the first one by -1
you can get → -x + 2y = 1

plus two sentences together
you can get → 2x = -2

so you are able to know that x = -1
and y = 0

PLEASE HELP: A standard six-sided die is rolled.
amm1812

Answer in fraction form is 1/3

Answer in decimal form is 0.3333

Pick one answer only.

==========================================================

Explanation:

The sample space is the set of all possible outcomes. In this case, the outcomes consist of values between 1 and 6

S = sample space

S = {1,2,3,4,5,6}

There are 6 items here. Let B = 6.

We want to roll a number greater than 4, so the event space we're after is

E = {5,6}

which consists of 2 items. Let A = 2.

The probability we want is A/B = 2/6 = 1/3 = 0.3333

So if you go with the fraction option, then you'll type in 1/3

If you go with the decimal option, then you'll type in 0.3333
