Question

Help please!! I'm failing Math!! I really need help!


A test consists of multiple choice questions worth 3 points and essay questions worth 5 points. The test has 17 questions that are worth a total of 65 points. Use a model to determine how many multiple choice questions are on the test.

Answer 1

i dont get how you are supposed to figure it out

Answer 2

in a normal test the maximum essays you get is 5 so i would say there's 12 multiple choice questions im not sure ( not using math just my head) lol

Answer 3

can anyone explain this please?

Answer 4

ok listen

Answer 5

you make 2 equations here
let multiple choice be x and essay be y
then there are 17 questions right?
so x+y =17
and
x is for 3 marks and y is for 5
total marks are 65
so 3x+5y =65
so now you have 2 equations x+y=17
and 3x+5y=65
solve them
you will get the answer
