Answer:
f=21-16, 5
Step-by-step explanation:
Just subtract 16 from both sides to get 5 as the solution
First lets see how many combinations there are that make 8 from the numbers 1-6:
2+6
3+5
4+4
5+3
and 6+2.
Note: the order does matter, because you roll two die. This means the first die has a number and the second die also has a number. 2 on 1st dice and 6 on 2nd dice would be a different combination than 2 on 2nd dice and 6 on 1st dice.
Now we calculate the probability of getting a number 2 through 6 on the first dice: which is 5/6.
Then calculate the probability of getting a number that pairs up with the first number to make 8: *Note: once you get a number 2 through 6, there is only one other number that you can roll to make 8. This means the probability of getting a match would be 1/6 on the 2nd dice.
Finally, multiply the two fractions we got earlier: 5/6 x 1/6 = 5/36
Your probability would be 5/36 in fraction form, 13.89% in percent form, or 0.139 in decimal form rounded 3 places.
Hope this helps, and May the Force Be With You!

Step-by-step explanation:
When using the Elimination method, you eradicate one pair of variables so they are set to zero. It does not matter which pair is selected:

{2x - 3y = 9
{⅖[−5x - 3y = 30]

------------------------------------------------------------------------------------------

{x - 2y = 10
{⅔[x + 3y = 5]

_______________________________________________

{y = −3x + 5
{−⅜[y = −8x + 25]

------------------------------------------------------------------------------------------

{y = −x + 1
{¼[y = 4x - 14]

Answer:
x = 2
Step-by-step explanation:
5(x + 1) = 4x + 7
5x + 5 = 4x + 7
x + 5 = 7
x = 2
