Just need help finding X and Y

Lapatulllka [165]

Answer:

Step-by-step explanation:

For x use the Pythagorean theorem:

$x^2+6^2=10^2$

$x^2+36=100$ <em>subtract 36 from both sides</em>

$x^2=64\to x=\sqrt{64}\\\\x=8$

We know: x + y = 20. Substitute:

$8+y=20$ <em>subtract 8 from both sides</em>

$y=12$

There are 16 students playing kickball. Two students leave to go play hopscotch. How do you write the fraction of children left

olga55 [171]

Answer:

7/8

Step-by-step explanation:

When 16 students are playing kickball, there are 16/16 students on the field. After 2 leave, this becomes 16-2/16, therefore 14/16 which is divisible by 2. and therefore 7/8, which the numerator and denominator have no common divisors.
