So we are trying to solve for x so in order to do that we need to get x by itself on one side of the equal sign
first we are going to combine like terms on each side of the equal side
so on the left side we see 4+9 these are booth whole numbers not attached to a variable so we can simplify this by adding these two values together making our equation: x/13 = 12
our x is still not by itself so in order to get it by itself we need to get rid of that 13
we need that x is being divided by 13 so in order to get rid a divided value we have to do the opposite to both sides - multiply by 13 on each side!
x/13 x 13 = x
12 x 13 = 156
so our equation is now:
x = 156
is our x by itself on one side of the equal sign? yes! so our x value is 156
Answer:
The 2nd option
Step-by-step explanation:
As x approaches postive and negative infinity, y approches negavite infinity
Answer:
Astronomers were trying to find the weight of six planets - Mars, Venus, Pluto, Jupiter, Mercury, and Saturn. The number of planets lighter than Mars was equal to the number of planets heavier than Venus. Saturn was heavier than Mars and Mercury were heavier than Pluto. Venus was lighter than Mars. Saturn was not the heaviest planet.
