Solve the following proportions: solve for x:
4/15=x/45

x=12

Step-by-step explanation:

First, you'll have to cross multiply.

4/15=x/45

4(45)=x(15)

180=15x

Next, you'll want to flip the equation.

15x=180

Finally, you'll want to divide both sides by 15.

15x/15=180/15

x=12

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

step-by-step explanation:

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
