Which of the models show 1.28 ÷ 4?
Talja [164]

Answer:

1.28 ÷ 4 = 0.32

But the "models" make little or no sense.  I can see the three bars and two dots representing the digits 3 and 2, but that is the only image I see, repeated three times.  It also shows no reference to the decimal place, so I would say there is no real representation of it all.

The total cost for two family cars was $71,1482 the cost of one car was $38,295 write an equation using a variable to represent
Harrizon [31]

Your 71,1482 doesn't make sense. But regardless,

let x = the other car's cost.

You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.

You can do $38,295 + c = $71,1482.

Or $71,1482 - $38,295 = c.
