Start by writing a formula-
30=(x+1)+(2x)+(3x+1)
Combine like terms-
30=6x+2
Subtract 2 from both sides
28=6x
Divide both sides by 6
4.666≈x
You can then check this by plugging in 4.666 to your formula and adding to see if it works. Remember, x is roughly equal to 4.666.

Fraction of the shape shaded on these two shapes??
xxTIMURxx [149]
The one of the left isn't too tricky, in the bottom left of it you have 1/2 of 1/4 of the shape, and on the bottom right you have 1/4 of 1/4. Imagine the whole shape was cut up like that bottom right bit into 16 triangles, then you would have three of them shaded (see my diagram).

The one on the right seems like guesswork to me, so I'm sorry if I'm wrong. It look like you just have to use your eyes to work out how much of the bottom half of the shape is shaded: looks like 1/16 to me (i.e. you can draw four of those along and four down, again, see my diagram.) So plus the top half, which is 8/16, you get 9/16.

Answers: left picture: 3/16.
                 right picture: 9/16.
