To simplify this:
You can factor the denominator and then cancel out some terms. But, this is not factorable. So, I think you are missing a term or you wrote this wrong.
Answer:
C
Step-by-step explanation:
Answer: 3 people ordered soup.
Step-by-step explanation:
Let x be the number of people ordered salad and y be the number of people ordered soup.
As per given,
x=2y (i)
7.50x+6.25y= 63.75 (ii)
Substitute value of c =2y in (ii) , we get
7.50(2y)+6.25y= 63.75
⇒ 15y+6.25y = 63.75
⇒21.25y = 63.75
⇒ y= 3 [divide both sides by 21.25]
Then, x= 2(3) =6
So 6 people ordered salad and 3 people ordered soup.
That equation has no graph. If it had a solution, the solution would be a single number. But that particular equation has no solution either ... there is no number that 'x' could be that would make the equation true.
Answer:
Just input sin(9), sin(30), sin(81), etc.
For this set, you need a scientific calculator or else, you won't be able to answer that. There is a way but that is already obsolete now.
