Answer:

Step-by-step explanation:

If you know perimeter, an area you can find by formula

s = P/2

A = \sqrt{s(s-a)(s-b)(s-c)}

If P ≈ 32.3177 units , then A ≈ 47.9 units²

Rolling 7 or 11 on the first roll is a win probability of winning on 1st roll
gtnhenbr [62]

1/6 plus 1/18, which equals to 2/9. Suppose we roll 4 on the first roll (the probability of rolling 4 is 1/12). On each successive roll the probability of rolling 7 is 1/6 and the probability of rolling 4 is 1/12.

[i.dk how this can help but if you got a 7 or 11 rolling on the first round you would probably win]

-3x + 3y = 4<br> -x+ y = 3
Natalka [10]

Answer:

No solution

Step-by-step explanation:

-3x + 3y = 4

-x + y = 3

<u>Solve the equation for x:</u>

<u>Move the variable to the right side and change its sign</u>

-x + y = 3

-x = 3 - y

<u>Change the signs on both sides of the equation</u>

-x = 3 - y

x = -3 + y

<u>Substitute the given value of x into the equation -3x + 3y = 4</u>

-3x + 3y = 4

x = -3 + y

-3(-3+y)+3y=4

<u>Solve the equation for y</u>

-3(-3+y)+3y=4

y = 0

There is no solution for y.

And since there's no solution for y, the system has no solution.
