Answer:

c. 10\frac{17}{18}

Step-by-step explanation:

-4\frac{5}{6} + 15\frac{7}{9}

Change to improper fractions.

\\-4\frac{5}{6} = -\frac{29}{6} \\

Multiply the whole number by the denominator and add that to the numerator.

15\frac{7}{9} =  \frac{142}{9}

Multiply the whole number by the denominator and add that to the numerator.

-\frac{29}{6} + \frac{142}{9}

6: 6, 12, 18\\9: 9, 18

Find a common denominator.

-\frac{29}{6} * 3 = -\frac{87}{18} \\\\\frac{142}{9} * 2 = \frac{284}{18} \\\\-\frac{87}{18} + \frac{284}{18}

-\frac{87}{18} + \frac{284}{18} = \frac{197}{18}

Add

10\frac{17}{18}

Simplify

I hope this helps! May I please have brainliest? :)

The 45°- 45° - 90° Triangle Theorem states that the length of the hypotenuse is ________ times the length of one leg.
Airida [17]
 <span>This is an isosceles triangle. If each side is 1, we can find the hypotenuse using the Pythagorean theorem. 

a^2 + b^2 = c^2 
1^2 + 1^2 = c^2 
1 + 1 = c^2 
2 = c^2 
root 2 = c 

Thus, the answer is root 2.

Hope this helps :)</span>
