there are 16 questions on a test. Each question is worth either 5 or 10 points. The total is 100 points. Let x= the number of 5 point questions and let y= the number of 10 point questions. Write a system of equations to find a number of each type of question
okay so 4 of them will be 10 point questions and 12 will be 5 point questions so lets say this. your equation is {(12x)+(10y)=100)} is x = 5 and y = 10. show that to your teacher she'll/he'll be impressed. enjoy :D
