SVETLANKA909090 [29]

If the number cube is rolled 18 times, then the number of unsuccessful rolls = 90 unsuccessful rolls.

Step-by-step explanation:

step 1: A cube has six faces and each face is numbered from 1 to 6.

step 2: The win in the game requires the number 6, when a cube is rolled.

step 3: On rolling a cube, the outcomes are (1,2,3,4,5, and 6).

step 4: Out of these outcomes, 5 are unsuccessful rolls (1,2,3,4,5) and 1 is a successful roll (6).

step 5: If the cube is rolled 18 times,

then the number of unsuccessful rolls = 18 * 5 unsuccessful rolls

= 90 unsuccessful rolls.

If 3 times a square of an integer is added to 1 times the integer, the result is 2

jarptica [38.1K]

Let unknown integer be n.

So then your sentence would translate to 3n² + n = 2.

If you need to solve for n then we can move 2 to left side by subtract both sides by 2:

3n² + n - 2 = 0

Now you can factor:

3n² + 3n -2n - 2 = 0

3n( n + 1 ) - 2( n + 1 ) = 0

( 3n - 2 )( n + 1 ) = 0

3n - 2 = 0 OR n + 1 = 0

3n = 2 OR n = -1

n = 2/3 OR n = -1

Final answer: n = 2/3 OR n = -1
