Round 57.8 to 60 and round 81 to 80.
60/80 or, if you simplify it, 3/4
And it is common knowledge that 3/4 = .75
So the quotient of 57.8/81 is ~.75
-6n-20=-2n+4-12n
-6n-20=-14n+4
+6n +6n
-20=-8n+4
-4 -4
-24=-8n
/8 /8
n=-3

Answer:
1. The other root is
2. c=-106
Step-by-step explanation:
The given equation is .
If is a solution to the given quadratic equation, then must satisfy this equation.
We now substitute into the given equation to obtain;
.
Comparing to the general equation;
, we have a=10, b=-33 and c=-106.
Recall the quadratic formula;
We now use the quadratic formula to obtain;
This implies that;
or
or
or
Hence the other root is
Answer:
d=-9
Step-by-step explanation:
you simplify both side of the equation
d/3-9=-12
1/3d+-9=-12
add 9 both sides
1/3d-9+9=-12+9
1/3d=-3
then you multiply 3 both sides
3 x (1/3d)=(3) x(-3)
d=-9
Hopes this helps :)
