Answer:

x(x+5)=x^2-3x+8

Step-by-step explanation:

There are infinite cases of equations with exactly one real solution. To create something worth the space, this one should suffice

x(x+5)=x^2-3x+8

Operating

x^2+5x=x^2-3x+8

Simplifying

5x=-3x+8

Joining like terms

8x=8

Solving

x=1

Testing the result

1(1+5)=1^2-3(1)+8=>6=6

elixir [45]

Answer: 1

Scotland

Step-by-step explanation:

In the first vote, points are:

France = 15

England = 12 + 16 = 28

Ireland = 19

2nd vote

England = 15

Scotland = 12 + 19 = 31

Ireland = 16

3rd vote

Scotland = 15 + 16 = 31

Ireland = 12

England = 19

4th vote

Ireland = 15

France = 12 + 16 + 19 = 47

At the end of everything

England = 19 + 15 + 28 = 62

France = 15 + 47 = 62

Scotland = 31 + 31 = 62

Ireland = 19 + 16 + 12 + 15 = 62

To find the Condorcet winner, the number of votes for runner over opponent (runner,opponent) is compared with the number of votes for opponent over runner (opponent,runner)  

Only Scotland has the highest (31) points twice.

(-11)-((-7)+5<br> help me solve please !!
nekit [7.7K]

Answer:

1 or -9, depends on the problem, see below.

Step-by-step explanation:

-11--7+5

Two negatives make a positive so our new equation is:

-11+7+5

-11+7 is -4, so:

-4+5

And this leaves us with:

1

But I saw there was a parentheses, was it misplaced or was one not added? If one was not ended to the end, then the answer would be different.

(-11)-((-7)+5)

-7+5 is negative 2, so:

-11-(-2)

Once again, two negatives make a positive, so our new equation would be:

-11+2

Which gets us:

-9
