Answer:
11th floor
Step-by-step explanation:
So to figure out what floor Rosa's office is in, we need to declare some variables.
x = Rosa's office
down 5 floors = -5
up 8 floors = 8
down 13 floors = - 13
One major clue to find Rosa's office is that she went down 13 floors to get to the 1st floor. So let's declare that Rosa is on the first floor.
x - 5 + 8 - 13 = 1
x - 10 = 1
x = 1 + 10
x = 11
So Rosa's office is at the 11th floor of the building.
Answer:
The equivalent expression 
Step-by-step explanation:
Given:
We need to find the equivalent for given expression.
Solution:
Now by using Law of indices which states;
So applying the same in given expression we get;
Now we can say that;
Also
Now We know that;
On substituting we get;
Hence The equivalent expression
Because by dividing both equations you get an answer of 8 for both
<h3>Answer: x < -2, choice B</h3>
===========================================
Work Shown:
10x + 18 < -2
10x + 18-18 < -2-18 ... subtract 18 from both sides
10x < -20
10x/10 < -20/10 ... divide both sides by 10
x < -2
