Write an equation for the following: the temperature is was 72° f and then dropped 2° per hour for the next eight hours.

so every hour it droped 2 degrees and it did this for eight hours you could times 2 by 8 and get 16 then minus it from 72

5x+2x=49

7x=49

x=7. 35 apples

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
