Answer:
The value of x is 
.
Step-by-step explanation:
It is given that the inverse variation equation is
..... (1)
The value of y is 4 and the value of k is 7.
Substitute y=4 and k=7 in equation (1).
Divide both sides by 4.
Therefore the value of x is .
Answer:
Step-by-step explanation:
If there is 1500 cellular phones per 1000 people, then the number of phones per person is:
Now we know that 
Y= 12 - x
27 + 3( 12 - x ) = 2x
Answer:
2 rides per hour
Step-by-step explanation:
This is a division problem since we would need to divide in order to answer the question.
Divide the amount of rides she rode to the number of hours she was there.
Input the numbers below:
amount of rides she rode/number of hours there
14/7=2
At this rate, Ramona rode 2 rides per hour.
3(y+10) = 3(3). For additional simplification, the answer may be written as
y+10 = 3
