There were 45 runners to start a race. In the first half of the race 2/3 of them dropped out. In the second half 2/5 of the remaining runners dropped out. How many runners finished the race?

Answers

Answer 1

Answer:

18 racers finished.

Step-by-step explanation:

In the first half, 30 racers dropped out, because 2/3 of 45 is 30. In the 2nd half, 12 racers dropped out, because that is 2/5 of 30. So, in the end, 18 racers finished. (I might have done this wrong i did my best)

3x + 10 = 4x +54. How did you get your answer?

Answers

Answer:

[tex]x=-44[/tex]

Step-by-step explanation:

[tex]3x+10=4x+54[/tex]

To solve for the variable [tex]x[/tex], start by subtracting [tex]3x[/tex] from both sides of the equation:

[tex]10=x+54[/tex]

Then, subtract [tex]54[/tex] from both sides of the equation:

[tex]-44=x[/tex]

Therefore, [tex]x=-44[/tex]

-

To check your work, simply substitute the solved value of [tex]x[/tex] into the initial equation:

[tex]3(-44)+10=4(-44)+54[/tex]

Multiply:

[tex]-132+10=-176+54[/tex]

Add:

[tex]-122=-122[/tex]

Since both sides of the equation are equal to each other, our solution is correct!

Answer:

[tex] = > 3x + 10 = 4x + 54[/tex]

We need to get the x on the one side and the numbers on the other.

Subtract 3x from both sides:

[tex] = > 3x - 3x + 10 = 4x - 3x + 54[/tex]

[tex] = > 10 = x + 54[/tex]

Subtract 54 from both sides:

[tex] = > 10 - 54 = x + 54 - 54[/tex]

[tex] = > - 44 = x[/tex]

Thus,the value of x is -44.

For checking:

[tex] = > 3x + 10 = 4x + 54[/tex]

[tex] = > 3( - 44) + 10 = 4( - 44) + 54[/tex]

[tex] = > - 132 + 10 = - 176 + 54[/tex]

[tex] = > - 122 = - 122[/tex]
