Jo just started collecting stamps. So far he
has 12 stamps. The number of U. S. stamps,
u, is 3 less than twice the number of foreign
stamps, f. How many of each type of stamp
does Jo have?

the answer

b. they are parallel and will never intersect.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
