Need ! a mountain climber is at an elevation of 10,000 feet. if she descends 2,000 feet a day, which equation would be used to show how many days it will take to reach sea level (0 feet)? 10,000 ÷ 2,000 -10,000 ÷ 2,000 -10,000 ÷ (-2,000) 10,000 ÷ (-2,000)

-10,000 / -2000, although 10,000/2000 gives the same answer.

Step-by-step explanation:

The equations -10,000/2000 and 10,000/-2000 are negative, and negative days do not make sense, thus eliminating those answers.

Also, she wants to descend 10,000 feet, so that makes it -10,000 int he equation.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

won't that be plagrisim thought?
