Answer:
12
Step-by-step explanation:
Add each number given = 132
132 / 6 (amount of given numbers)
=12
So?
-756*x +x =1 ?
-755 x = 1
x= -1/755
or
what two numbers when multiplied equal -756 but when added together equal 1?
numbers are x and y
x*y= -756
x+y=1
rearrange the 2nd eq
y=1-x
substitute
x(1-x)=-756
distribute
x-x^2=-756
solve for zero
x^2-x-756=0
factor/quadratic equation
70--you have to round down because its ".2" and not ".5 or above"
