Answer:
D. 1/2
Step-by-step explanation:
Because if you choose A , you get +4
if you choose B ,you get -12
Choose C , you get +20
D is the correct answer.
They ate 13 hot dogs in 2 minutes, so divide 13 by 2 to find out how many hot dogs he ate in 1 minute:
13 / 2 = 6.5 hot dogs per minute.
Now divide total hot dogs eaten by 6.5 to get the total time:
91 / 6.5 = 14 total minutes.
The factors of 96 are 3,5,7
let the number is 10x + 3.
then sum of its digits = x + 3.
from given condition, we have
x+3 = (1/7)* (10x + 3)
=> 7x + 21 = 10x + 3
=> 3x = 18
=> x = 6
therefore the number is 63.
