Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete - Hello Friend question and answers, In sharing this time titled Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete, in helping to answer a question or help learning, hopefully content posting subject matter that I share this you can understand, if there are any difficulties please to comment.
Your Question : Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete
Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. What is the equation that
can be used to find the value of y, the total time that Vlad spent on his homework, and what are the constraints on the values of x and y?
Answer:
So the total time of the homework is y, as is specified in the task
we know that y= 20 mins + x*2 mins (20 minuts for the history homework and then x math questions, each of 2 mins lenght), so this is our equation:
y= 20+ x*2
The number of the math problems cannot be negative: so the value of x cannot be negative (and also, it is presumably at least two, as he solved problems, in plural
so, x≥2
This means that y≥20+2*2, so y≥24.
