Answer:
13.44 or 13 11/25 hours
Step-by-step explanation:
First use this format: number of essays/hours
- they are asking if all three work together, how many hours would it take, so this means addition:
50/7 + 50/14 + 25/6 = 200/x
Second, solve:
- least common multiple: 42
300/42 + 150/42 + 175/6 = 200/x
625/42 = 200/x
- cross-multiply
625x = 8,400
x = 336/25 = 13 11/25 = 13.44 (any one of these answers would work)

I think option 4 is the correct answer
Answer:
use multiple the numbers to get the co rrect
Step-by-step explanation:
32×6
=192
29×7=203
Distance traveled in 35 minute = 2 miles.
So distance traveled in one minute = 2/35 (miles/minute)
= 0.0572 miles / minute.
So distance traveled in one hour , we can find by multiplying it from 60.Because in one hour there is 60 minute.
SO distance traveled in one hour = 0.0572 * 60
= 3.432 miles / hour.
Differentiate both sides with respect to <em>x</em>, assuming <em>y</em> = <em>y</em>(<em>x</em>).
Solve for d<em>y</em>/d<em>x</em> :
If <em>y</em> ≠ 0, we can write
At the point (1, 1), the derivative is
