It took me a while to work that one out lol

$$|x+2|\ge 8$$

This says "The absolute value of (x+2) is greater than or equal to 8.

This means that x+2 must be further from zero (or equal to) on the number line than 8 as shown on this number line.

So 

$$\begin {array}{rlllrll}
x+2 &\le& -8\qquad &or& \qquad x+2&\ge& 8 \\
x+2-2 &\le& -8-2\qquad &or& \qquad x+2-2&\ge& 8-2\\
x &\le& -10\qquad &or& \quad \qquad x&\ge& 6\qquad
\end{array}$$

Try looking at this site

r+13/4=5/2

SUBTRACT 13/4 from both sides

r=5/2 - 13/4

r=10/4-13/4

r= -3/4

If you have 13 divided by 4 the answer is 3 remainder 1  This is normally written as     $$3\frac{1}{4}$$

BECAUSE

If you have 13 cakes and split them between 4 people

they each get 3 cakes but there is 1 left over

If that one is cut into quarters then they also get 1/4 of a cake each.

OH

AND I LOVE YOUR BRIGHT PICTURE!!

I LOVE MATH TOO!!

Is there a question here?

Or you can draw the right angled triangle and get the exact value on the 3rd side using pythagoras and 'read' the cos off the triangle.

Good one Chris. 

The question is incomplete. sorry

1/4 

that is the answer
