Y=30x+18
well if he didn't deliver to any houses he would be paid 18$.
Answer: 
Step-by-step explanation:
The equation for inverse variation is:
Where "k" is the constant of variation.
If you solve for for the constant "k", you get the form:
So, if 
then 
Knowing the value of "k", you can find the value of "x" when 
, by substituting these values into the equation .
Therefore, you get that the value of "x" when is:
Answer:
B. Doubled
Step-by-step explanation:
The formula to find the circumference of the circle is
Now our problem says that the radius is doubled. Hence the new radius is 2r
Hence the new circumference will be
Hence our circumference gets doubled.
Sol. (1) Prime factors of 26 = 2 x 13
Prime factors of 91 = 7 x 13
Hence, HCF = Common factors between 26 and 91 =13 and LCM=13x2x7=182
Now product of numbers 26 and 91
= 26 x 91 = 2366 and Product of HCF and LCM = 13 x 182 = 2366
So, it verify that product of two numbers = Product of HCF and LCM.
(2) Prime factors of 510 = 2 x 3 x 5 x 17
Prime factors of 92 = 2 x 2 x 23
Hence,HCF=2 and LCM=2×2×3 × 5×17×23 =23460
Now product of Numbers 510 and 92 = 46920 and product of HCF and LCM = 2 x 23460= 46920
Hence, verified that product of two numbers 18 equal to product of their HCF and LCM.
(3) Prime factors of336 = 2 x 2 x 2 x 2 x 3 x 7
Prime factors of 54 = 2 x 3 x 3 x 3
Hence, HCF (Product of common factors of 336 and 54)
=2 x 3=6
And LCM (Product of all common factors with remaining factors)
=(2 x 3)x 2 x 2 x 2 x 3 x 3 x 7=3024
Now, product of numbers 336 and 54 = 336 x 54 = 18144
and product of HCF and LCM = 6 x 3024 = 18144
Hence, product of two numbers: Product of HCF and LCM.
