A car is tràveling a speed of 55milied per hour write an algebraiv expression to show how far the car will travel in a certain number of hours what will be constant and variable

D = 55T

Step-by-step explanation:

To write an algebraic equation for the information, we need some specific variables. These are the distance, the time taken and the speed( rate)

Let the distance be D, the time be T and the speed be S

Since our distance equals the product of the speed and time, ordinarily, our equation is D = ST

But we have the value for the speed already since it is a constant. Thus

D = 55T

At anytime T, the distance traveled equals the product of the Time by 55 which is the speed.

The constant term is S which is 55. The variable terms will be the T and D, with D being the distance traveled and it is dependent on T which is the time

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
