Answer:

12:21 is your answer.

Step-by-step explanation:

33 photos in a 4x to 7x ratio

4x + 7x = 33

11x = 33

x = 3

33 photos can be put in a 4(3) to 7(3) ratio

which is a 12 to 21 ratio

so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7

Note:

a(b) = ab = a x b = a times b

balu736 [363]

Answer:

I think its D)

Step-by-step explanation:

7x−3y+2=0

Add -7x to both sides.

7x−3y+2+−7x=0+−7x

−3y+2=−7x

Add -2 to both sides.

−3y+2+−2=−7x+−2

−3y=−7x−2

Divide both sides by -3.

−3y /−3 = −7x−2 /−3

which equals d)
