Answer:
More generally, when a carbon atom is bonded to four other atoms, the molecule (or part of a molecule) will take on a tetrahedral shape similar to that of methane. (if this doesn't help sorry :<)
The statement above is TRUE.
When heat is added to a substance, the heat increases the kinetic energy of the particles of the substance and enable to vibrate or move faster, this usually increase the temperature of the substance. However, adding heat does not always increase the temperature of a substance. For instance, during the process of boiling point of water, the additional heat energy that is added to the water is used to break the chemical bonds in water and not to increase the temperature of water.<span />

Sharon earns $25 per item. This means that this number is increasing with each item sold, then you will have a variable with this number, such as 'x'.
Plus a base salary of $100 per week. This means that this number is always true for each week and will not change when looking at a weekly perspective.
How many items must she sell to earn at least $700 per week. This is the end goal or even slightly over $700.
To set it up:
25x + 100 ≥ 700
To solve:
25 x + 100 ≥ 700
- 100 -100
______________
25x ≥ 600
___ ___
25 25
_______________
x ≥ 24
Interpret:
Sharon must sell at least 24 items.
