Can u solve
2x+13=-7x+28

Step-by-step explanation:

2x+13=-7x+28 =

Solutions:

x = 15

     9

≈ 1.666667

x= 5/3

Step-by-step explanation:

subtract 13 from both sides of the equation

2x+13=-7x+28

2x+13-13=7x+28-13

simplify

subtract the numbers

2x=-7x+15

add 7x to both sides of the equation

2x+7x=-7x+15+7x

simplify

9x=15

divide

9x/9 = 15/9

simplify

Cancel terms that are in both the numerator and denominator

divide the numbers

x=5/3

tangent

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
