The amount of time spent doing warm ups is 15 minutes, and the total amount of time doing the workout is 65 minutes. Plug these two numbers into the ratio and simplify.
The ordered pair is indeed a solution to the system:
.
Step-by-step explanation:
Consider a system of equations about variables and . An ordered pair (where and are constant) is a solution to that system if and only if all equations in that system hold after substituting in and .
For the system in this question, would be a solution only if both equations in the system hold after replacing all in equations of the system with and all with .
The of the equation would become . The of that equation would become . The two sides are indeed equal.
Similarly, the of the equation would become . The of that equation would become . The two sides are indeed equal.
Thus, and simultaneously satisfy both equations of the given system. Therefore, the ordered pair would indeed be a solution to that system.
Convert 2/5 to a decimal and you get .4, or 40%. 40% of the band members also sing, so yes, the band has the same number of string instrument players and singers.
