You have to complete at least 10 physics problems and math problems within 2 hours before you playing video games. It will take you 20 minutes to complete a physics problem and 10 minutes to complete a math problem. Write a system of inequalities to express this situation. What is the most possible number of physics problems you can complete and still meet the requirements?

2

Step-by-step explanation:

Given

Physics problem requires 20 min

Math problem require 10 min

suppose x question of Physics and y questions of Math are done

so according to the question

Time require for x Physics problem

Time require for y Math problem

so,

On solving (1) and (2)

we get and

Maximum no of Physics question which can be solved is 2

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
