One number is 7 more than another number. the sum of the numbers is 63. what is one of the numbers

let one number = x, let another number = y

x = y + 7 , x + y = 63

Plug in y + 7 for x

(y + 7) + y = 63

Simplify

2y + 7 = 63

Isolate the y. Note the equal sign. What you do to one side you do to the other

2y + 7 (-7) = 63 (-7)

2y = 56

2y/2 = 56/2

y = 28

As you are only asking for one of the numbers, 28 is your answer. The other is 35.

hope this helps

worked it out i believe

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
