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:
5m - 250 = 30
Solution:
Meaning of the solution in words:
It will take her 44 minutes to have 30 weeds remaining.
To solve this problem, we can set up an equation:
5m - 250 = 30
where m represents the number of minutes it takes for Grandma to remove the weeds.
To isolate m, we can add 250 to both sides of the equation:
5m - 250 + 250 = 30 + 250
This simplifies to:
5m = 280
Now we can divide both sides of the equation by 5 to solve for m:
5m/5 = 280/5
This gives us:
m = 56
The solution to the equation is m = 56, which means it will take Grandma 56 minutes to have 30 weeds remaining in the garden.
To find the number of minutes it will take Grandma to have only 30 weeds remaining in the garden, we can use the equation:
5m - 250 = 30
Where m represents the number of minutes it will take.
To solve for m, we can start by adding 250 to both sides of the equation:
5m - 250 + 250 = 30 + 250
This simplifies to:
5m = 280
Next, we isolate the variable m by dividing both sides of the equation by 5:
5m/5 = 280/5
This simplifies to:
m = 56
Therefore, it will take Grandma 56 minutes to have only 30 weeds remaining in the garden.
