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
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.
To solve the equation for the number of minutes it will take Grandma to only have 30 weeds remaining in the garden, we need to use the equation: 30 - 5m = 250.
To isolate the variable "m," we need to move the constant term 30 to the other side of the equation by adding it to both sides:
30 - 5m + 5m = 250 + 30
-5m + 5m + 30 = 250 + 30
This simplifies to:
30 = 280 - 5m
Next, we need to move the constant term 280 to the other side of the equation by subtracting it from both sides:
30 - 280 = 280 - 280 - 5m
-250 = -5m
To solve for "m," we need to isolate the variable. We can do this by dividing both sides of the equation by -5:
-250 / -5 = -5m / -5
50 = m
Therefore, it will take Grandma 50 minutes to only have 30 weeds remaining in the garden.
