4/3
Step-by-step explanation:
80 to 60 means a ratio. That means 80:60, which means 80/60, which simplifies to 4/3.
Answer:
$25
Step-by-step explanation:
well you have to identify what the method is first.
He is basically pricing things by the count of 5. So, you can assume that it would cost $25.
Idk, this is a weird problem
9.725 would be the answer
Answer:
If your question is set up like this 
then your answer is No solution.
If your question is set up like this
then your answer is 
or x = 0.765
Hope this helps!
The number of solutions of a quadratic equation
ax^2+bx+c=0
Depends on its discriminant
/Delta=b^2-4ac
If /Delta>0 there are two distinct solutions
If /Delta=0 there are two coincident solutions
If /Delta<0 there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:
