![]() ![]() We can solve this system of equations 3 ways: Since total points = points per problem * number of problems, we're given 2 equations: Let s be the number of short response questions Let m be the number of multiple choice questions Write a system of linear equations that represents this situation The multiple choice questions are worth 3 points each and short response questions are worth 8 points each. how many sĪ 100 point test contains a total of 20 questions. Whichever method you choose, you get the same answer:Ĥ5 students, 12 taking spanish, 15 taking chemistry, 5 taking both spanish and chemistry. Let the number of children who used the pool be c, and the number of adults who used the pool be a. How many adults and children used the pool Daily prices are $1.75 for children and $2.00 for adults. Using our GCF Calculator, we see this fraction can be reduced by 5Ĭalculate Expected Number of Item B:Ĭalculate Expected Number of Item C: Therefore, our total group is 1 + 2 + 2 = 5Ĭalculate Expected Number of Item A: Given the ratio 1 : 2 : 2, calculate the expected number of items from a population of 100Ī ratio of 1 : 2 : 2 means that for every of item A, we can expect 2 of item B and 2 of item c
