Adam, beth, and carly walked a total of 10 miles collectively. beth walked twice as far as adam, and she walked a half a mile further than carly. if a = number of miles adam walks, b = number of miles beth walks, and c = number of miles carly walks, which equation is not true for this situation?
a) b = 2a
b) b = c + 0.5
c) 3a + c = 10
d) a + 2c = 10.5

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
