Questions

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:
30-5m=250
250+5m=30
5m-250=30
250-5m=30

1 answer

The correct equation is: 250 - 5m = 30

To solve for m, you need to isolate the variable on one side of the equation. You can do this by subtracting 250 from both sides:

250 - 5m - 250 = 30 - 250
-5m = -220

Next, divide both sides of the equation by -5:

-5m / -5 = -220 / -5
m = 44

Therefore, it will take her 44 minutes to only have 30 weeds remaining in the garden.
