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 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 set up an equation to solve this problem:
Let x be the number of minutes it will take Grandma to remove all but 30 weeds.
The number of weeds after x minutes can be represented by the equation: 250 - 5x = 30
Simplifying the equation:
-5x = 30 - 250
-5x = -220
Dividing both sides by -5:
x = (-220)/(-5)
x = 44
Therefore, it will take Grandma 44 minutes to remove all but 30 weeds in the garden.
Equation:
Let x be the number of minutes it will take Grandma to remove the weeds until there are only 30 remaining.
250 - 5x = 30
Solution:
To find x, we can rearrange the equation:
250 - 30 = 5x
220 = 5x
Dividing both sides by 5:
x = 220/5
x = 44
Meaning of the solution in words:
It will take Grandma 44 minutes to remove the weeds until there are only 30 remaining in the garden.
