Basically adding a negative means subtracting and vice versa so
-13+-11=-13-11=-24
The mountain climber has travelled 75 feet below sea level while descending down a cliff.
Given:
- A mountain climber at sea level starts descending down a cliff.
- Her location can be represented by -75 ft.
To find:
The distance travelled by a mountain climber.
Solution
- Distance ascending above sea level is taken in a positive direction.
- Distance descending down sea level is taken in a negative direction.
- This negative and positive only represents the direction
The location of mountain climber after descending from cliff = -75 ft
The distance covered by the mountain climber = 75 ft
The mountain climber has travelled 75 feet below sea level while descending down a cliff.

The sales tax rate of an item that costs $4 is 8%
<h2>
Explanation:</h2>
- An item costs $4 before tax
- The same item costs $4.32 after sales tax.
So the tax rate can be calculated as:
Tax rate = $4.32 - $4 = $0.32
Next, you must divide the tax rate by the original price in order to get the sales tax rate:
Sales tax rate = $0.32/4$ = 0.08
In percentage:
Sales tax rate % = 0.08x100% = 8%

Answer:
1 1/8 cups of brown sugar!
Explanation:
If the recipe calls for 2/3 white sugar for every 2/4 brown sugar, then we need to find the ratio really!
So do
3/4/2/3
( three fourths OVER two thirds ) 3/4 is the numerator and 2/3 is the denominator.
You get x=1*c
Finally do
3/4*3/2=x=9/8
Simplify 9/8 to 1 1/8.
Since you will need 1 1/8 cups of brown sugar for cup of brown sugar, you need 1 1/8 cups of brown sugar.
Answer: You will need 1/18
