Real world example could be:
Consider x is time in minutes
Consider y is the amount of fish food required in grams
The equation could then represent how much food (in grams) that a fish needs to be fed x minutes after it was previously fed.
Answer: is it -3,11
Step-by-step explanation:
4 pencils . 4/9 of an hour = 4/9 of 60 minutes = 4/9 * 60 = 80/3 minutes
x pencils = ? . one hour = 60 minutes
14 * 60 = 80/3 * x /*3
14 * 60 * 3 = 80 * x
80 * x = 2520 /80
x = 2520 / 80
x = 31.5 pencils
The result would be 32 pencils in one hour.
Answer:
1 mile = 0.2 hours
Step-by-step explanation:
Given that,
Eddie can travel 20 miles in 4 hours.
We need to find how many hours does it take Eddie to travel 1 mile.
20 mile = 4 hours
1 mile = (4/20) hours
= 0.2 hours
So, to travel 1 mile will take 0.2 hours.
(8 x 320)^1/3
(2560)^1/3
(64*40)^1/3
64^1/3 *40^1/3
4 * (8^1/3) * 5^1/3
4 * 2 * 5^1/3
8 *5^1/3
