It takes 0.15625 minutes to paint 1 square feet
<em><u>Solution:</u></em>
Given that, I can paint 96 sq ft in 15 minutes
To find: Time taken to paint 1 square feet
From given,
96 square feet is painted in 15 minutes
Let "x" be the time taken to paint 1 square feet
Then, we can say,
96 square feet = 15 minutes
1 square feet = x minutes
This forms a proportion and we can solve the sum by cross multiplying
Thus it takes 0.15625 minutes to paint 1 square feet
State the given in the question
Given that the sum of a number and 3 is subtracted from, the result is 5
State what is to be found in the question
We are to find the number. In other to achieve this, we would follow the steps below:
Step 1: Represent the number with an unknown
Let x represent the number
Step 2: Interpret the given statement mathematically
If x is the number, then the sum of the number and 3 would be
Then the sum of a number and 3 subtracted from 10 would be
Finally, when the sum of a number and 3 subtracted from 10, the result is 5, would be
Step 3: Solve for x in the mathematical interpretation of the given statement
The value of x is as calculated as shown below:
Hence, the number is 5
