To find the answer, see if the point is going to the left or to the right. If it is going to the left, it is less than. If it is going to the right it is greater than. Next find if the point is closed (shaded in) or open (not shaded in). If it is closed, it is equal to, if it is open, it is not equal to. Ex: Closed to the right - Greater than or equal to.
1) x is less than -7
2) x is less than or equal to 4.5
3) x is greater than -5
4) x is greater than 1.5
The area of a shape is the amount of space it can occupy.
<em>Laura's design will be light enough</em>
The shape is given as a trapezium (see attachment).
First, calculate the height (h) of the trapezium using the following Pythagoras theorem
Where:
So, we have:
Collect like terms
Take square roots
The area of the shape is then calculated as follows:
The area of the shape is 49 square inches.
<em>Hence, the shape will be light enough (because 49 is less than 80)</em>

3(x-7)+8=-20
Multiply the bracket by 3
(3)(x)(3(-7)+8= -20
3x-21+8= -20
3x-13= -20
Move -13 to the other side. Sign changes from -13 to +13.
3x-13+13= -20+13
3x= -7
Divide by 3
3x/3= -7/3
x= -7/3 or in mixed number : -2 1/3
Answer : x= -7/3 or in mixed number : -2 1/3
