Answer:
Step-by-step explanation:
Say your going to a concert and parking is nine dollars and it cost 7.50 for every person in the car. Use y as the number of people in your car
Answer:
y = 1
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 25 when x = 
, then
25 = 
= 5k ( divide both sides by 5 )
5 = k
y = 
← equation of variation
When x = 5, then
y = 
= 1
Answer:
20x
Step-by-step explanation:
You would multiply 1/4 times 8. Or instead, you could divide 80 by 4. You would get 20 then you would multiply that by x and get 20x. Hope this helps.
