-3z - (-z - 2)
In order to find the expression equivalent to our given expression, we have to simplify our given expression :)
-3z + z + 2
**Remember : the "z" and "2" become a positive because a negative times a negative is always a positive!**
Now, add like terms.
(-3z + z) + 2
Simplify.
-2z + 2
Look at our given answer choices.
Our answer is c. -2z + 2

Arrange the data set from least to greatest:
{45, 58, 70, 100, 450, 600, 805}
Find the median by canceling out until 1 or 2 values remain in the middle of the set:
{58,70,100,450,600}
{70,100,450}
{100}
The one value left is our median
We know that
<span> the highest that this mountain can be is 27849 feet
because this number (27849 feet) rounded </span>to the nearest hundred is 27800 feet, however if the number were 27850 the number rounded to the nearest hundred would be 27900
hence
the answer is
27849 feet
B is not a solution to the graph
Mike used the greatest amount, which is 70%
Multiply both numerator and denominator by 100
(0.7× 100)/100 = 70/100= 70%
