Answer:

  k = -1

Step-by-step explanation:

Subtract 10 and simplify. We choose this value so the constants on the right add up to give 0.

  3 -10 = 3 + 7k + 7 -10

 -7 = 7k

Divide by 7.

  -7/7 = 7k/7

  -1 = k

Bryan completed a 100-meter race in 11.74 seconds. Luis completed the same race in 11.69 seconds. What was the difference betwee
son4ous [18]

Answer:

\frac{1}{20} of a second

Step-by-step explanation:

We can convert each time into fractions.

11.74 is the same thing as 11 \frac{74}{100}

and 11.69 is the same thing as 11 \frac{69}{100}.

We know that 11 - 11 = 0, so we can focus on the fractions for now.

Let's subtract \frac{69}{100} from \frac{74}{100}.

\frac{74}{100} - \frac{69}{100} = \frac{5}{100}.

We can now simplify \frac{5}{100} by dividing both the numerator and denominator by 5.

\frac{5\div5}{100\div5}  = \frac{1}{20}.

Hope this helped!

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.So the equation to solve this would be simply 90 multiply 2 which gives you the answer of 180 degree in this situation.
