The photographer got the baby to smile in 30% of the photos he took. If the baby smiled in 12 photos, how many photos did the photographer take? Please explain and I will give the brain thing

Let x = total photos taken

30% = 0.30

0.30x = 12. Divide each side by 0.30

x = 40.

The photographer took 40 photos

40 photos

Step-by-step explanation:

Divide 12 by 3=4

4 is 10%

4x10 is 40 (or 100%)

Have a great day!

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
