Sam has 12 black and white photos and 18 color photos. he wants to put the photos in equal rows so each row has either black and white photos only or color photos only. in how many rows can sam arrange the photos

Step-by-step explanation:

First you have to find the GCF (greatest common factor) and the GCF is 6

Then you have to multiply 3×6 = 18, 2×6 = 12

Next add 3 + 2 = 5 because I added the first digits of the multiplying thinge

Write it like this (if you want):

Sam can arrange his photos in 5 rows

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
