digit at tens place of two digit number is twice the digit at units place .if sum of this number and the no.formed by reversing
Dima020 [189]
Let the number be     xy ,

xy = 10x + y.   when reversed = yx = 10y + x

x = 2y          ........(a)

10x + y + 10y + x = 66.........(b)

10(2y) + y + 10y + 2y = 66

20y + y + 10y + 2y = 66

33y = 66

y = 66/33

y = 2

x = 2y = 2*2 = 4

Recall the original number is xy =     42.

What is the best estimate for the number of people in line at 7.A.M
Keith_Richards [23]

We have been given the equation

y=-5.131x^2+31.821x-3.333

It represents the number of people standing to catch a commuter train x hours after 5 A.M.

Now, in order to find the number of people in line at 7 a.m. , we need to substitute x= 2 in the above equation.

y(2)=-5.131(2)^2+31.821(2x)-3.333\\y(2)= 39.785 \approx 40

Therefore, the number of people in the line at 7 a.m. is 40

D id the correct option.
