A wreck occurred on an interstate Highway that caused a traffic jam 1 mile long. The average car is 14 feet long and cars make up 70% of the Traffic Jam. The average Pickup Truck is 20 feet long and is 20% of the traffic jam. The average tractor Trailer is 75 feet long and makes up 10% of the traffic jam. If there are 3 feet between each vehicle, how many vehicles are in the traffic jam? A) 27 vehicles

C) 2700 vehicles

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
