film processing costs $4.95, plus $0.35 for each picture printed. Milan paid $11.95 for processing and printing. How many pictures did he have printed?

20 pictures.

Step-by-step explanation:

In this question, we need to find out how many pictures Milan printed.

We know that the film processing costed $4.95 and each picture that was printed costed $0.35.

Lets turn this into an equation with x representing the amount of pictures:

y = 0.35x+ 4.95

Now we need to solve the equation. We can do this by plugging in our known cost, 11.95, into "y".

Solve:

11.95 = 0.35x + 4.95

Subtract 4.95 from both sides.

7 = 0.35x

Divide both sides by 0.35

20 = x

Milan printed 20 pictures.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
