9
Step-by-step explanation:
I replaced the missing variable with x and solved the equation from there.
Answer:
Answer D (the fourth one)
Step-by-step explanation:
First, we need to set up a (y−k)^2=4p(x−h). After plugging in all of your values, you would get (x-5)^2=-4(y-1). Now, we need to solve in terms of y by dividing each side by the factors that don't contain the variable. Your final solution should be 
Answer:
<em>We can't find a unique price for an apple and an orange.</em>
Step-by-step explanation:
Suppose, the price of an apple is
and the price of an orange is 
They need $10 for 4 apples and 4 oranges. So, the first equation will be.......

They also need $15 for 6 apples and 6 oranges. So, the second equation will be........

Dividing equation (1) by 2 on both sides : 
Dividing equation (2) by 3 on both sides : 
So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for
and
here. Both
and
have <u>"infinitely many solutions"</u>.
Thus, we can't find a unique price for an apple and an orange.
30 is the answer
6*5\6 is 5
And 30 is needed to be multiplied y one to get five
Your answer would be 5 hours. Because total time divided by rate is the time it took to travel that distance. 250mi/50mph=5hours. Hope this helps.
