<em> - 2 1/3</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>6 2/9 : ( - 2 2/3) =</em>
<em>= (6*9+2)/9 : -(2*3+2)/3</em>
<em>= 56/9 : - 8/3</em>
<em>= 56/9 × - 3/8</em>
<em>simplify 56 - 8 ; 9 - 3</em>
<em>= 7/3 × - 1/1</em>
<em>= - 7/3</em>
<em>= - 2 1/3</em>
<em>Good luck !</em>

Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots
Answer:
Mikhail is 25 and Gabrielle is 15
Step-by-step explanation:
g = (m-10) and g+m = 40
We'll substitute that first equation into the second
(m-10) + m + 40
2m - 10 = 40
2m = 50
m = 25
