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.

To answer the question we make the sum on the left side of the equation:

Since both sides are exactly the same. this equation is always true.
So perimeter is adding all sides
In this picture, you have all sides, so add them up!
(2a-3)+(3a+1)+(2a) = P
So this expression shows that we're adding all sides that gives us the P, or perimeter :)
Answer:
Inequality: 25x + 30 < 155
Step-by-step explanation:
25x is the cost per lesson. 30 is the recital fee. 155 is the total cost. We used the < sign because she has to pay <u>LESS </u>than $155.
Solve...
25x + 30 < 155
Subtract 30 on both sides...
25x < 125
Divide 25 on both sides...
x < 5
<u>THATS NOT YOUR ANSWER YET </u>Always make sure to plug in the answer you got BEFORE inputting it.
Plug in 5 for x...
25 ( 5 ) + 30 < 155
125 + 30 < 155
155 < 155
You know that she wants to spend LESS than $155, when she takes 5 lessons, as shown above, she spends exactly $155, your answer would be 4 because she spends less than $155 when taking 4 classes, but exactly $155 when taking five.
Really hope this helps! :)
