Answer: 50 meters

Step-by-step explanation: 2 is the amount of meters climbed every minute, for example 2 * 10 (x) = 20 meters in 10 minutes. So the starting point is 50 meters above sea level.

<span>The expression 2x + 50 represents the elevation above sea level of the climber. It can be written as a function as follows:

f(x) = 2x + 50 where f(x) is the height and x is time.

We can obtain the initial height when we set time 0 in which the climber has not started climbing yet. Therefore, the initial height of the climber would be 50 meters above sea level.</span>

Find the difference in simplest form for 3/5-1/7
morpeh [17]

Answer: 0.457

multiply 3 by 7, and get 21

multiply 1 by 5, and get 5.

5 × 7 = 35.

fraction: 21/35 and 5/35

Subtract the numerators

21 − 5 = 16 = 16/35

Now we need to simplify the fraction that we have.

17 is larger than 16. So we're done reducing numbers.

<em>Our final answer: </em>16/35<em />

Hope this helps!

I am joyous to assist anytime.

Why do you need 23 days to count from 1 to 1 million?
Katyanochek1 [597]
This question is ambiguous. The time to count to 1 million could be more or less then 23 days. However, if someone counted to 1 million in 23 days nonstop, the interval between saying the next number would be 2 seconds.
