There were 56 runners to start a race. In the first half of the race, h of them dropped out. In the second half of the race, z of the remaining runners dropped
out. How many runners finished the race?

Answers

Answer 1

Answer:

56-h-z runners

Step-by-step explanation:

The only number we're given is 56, so the only thing that we can do is create an expression

Answer 2

Answer:

56 - h - z

Step-by-step explanation:

-h - z is the number of people who dropped out at any time in the race.

56 is the total amount, and you put -h - z behind it.

Therefore, you get 56 - h - z.

Answer:

(3, 9)

Step-by-step explanation:

First, what does it mean to move left 5 units from your starting position?

Second, how does that change were you are at this point?

ok so I start at (8, 9). I move left 5 units. Where do I end?

Since moving to the left changes my x variable, subtract 5 from 8

8 - 5 = 3

so that means my final position is at (3, 9)

What is problem-solving?

Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.

Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

Answers

Answer:

12.3246

Step-by-step explanation:

The equation to be solved is [tex]x^{2} -10=4x[/tex]

Rearranging: [tex]x^{2} -4x-12=0[/tex]

The quadratic formula is one way to solve this equation.

[tex]x=\frac{-b+\sqrt{b^{2} -4ac} }{2a}=\frac{12+\sqrt{12^{2}-4*1*4} }{2*1}[/tex]

Note that only the positive variation of the quadratic formula was used. This is because it is the only variation of this formula that produces a positive result for this equation. This is not always true, so it is best to work both versions of the formula for problems like these.

[tex]x=\frac{12+\sqrt{160} }{2} =\frac{12+4\sqrt{10} }{2}=6+2\sqrt{10} =6+6.3246=12.3246[/tex]

If the negative version of the quadratic equation was used, the final (incorrect) answer would be x= -0.3246.
