Grandma is removing weeds from her garden. She estimates that there are 250 weeds in the garden at the moment, and she can remove weeds at a rate of 5 per minute. At this rate how many minutes (m) will it take her to only have 30 weeds remaining in the garden?(3 points)
Equation:
Solution:
Meaning of the solution in words:
Let's denote the number of minutes it takes for grandma to remove 30 weeds as m.
Since grandma can remove 5 weeds per minute, we can write the equation: 5m = 250 - 30
Simplifying the equation, we have: 5m = 220
Dividing both sides of the equation by 5, we find: m = 44
Therefore, it will take grandma 44 minutes to only have 30 weeds remaining in the garden.
Equation: (250 weeds - x weeds) / 5 weeds per minute = m minutes
Solution: (250 - 30) / 5 = m
Meaning of the solution in words: It will take Grandma (m) minutes to remove all but 30 weeds from the garden.
