Im not sure but i believe its 690
Answer:
Step-by-step explanation:
6/9+x=7/10
x=7/10-6/9
when adding fractions both denominators must be equal, we’ll make them 90
x=(7/10)(9/9)-(6/9)(10/10)
x=63/90-60/90
x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3
x=(3/3)/(90/3)
x=1/30
we know that
In a quadratic equation of the form 
the discriminant is equal to
if 
-------> the equation has two real number solutions
if 
-------> the equation has one real number solution
if 
-------> the equation has two complex number solutions
In this problem we have
so
substitute in the formula
----> the equation has two real number solutions
therefore
<u>the answer is</u>
the equation has two real number solutions
