The sum of two numbers is 60. The greater number is 6 more than the smaller number. Which equation can be used to solve for the smaller number? a. x + (x + 6) = 60
b. x − (x + 6) = 60
c. x(x + 6) = 60
d. x(x− 6) = 60

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

x coordinate is none

step-by-step explanation:

the scale is 1/9 my friend can't simplify 1 anymore so it will be (for every 1 there's 9)
