Solving by Substitution Mr. Martin's math test, which is worth 100 points, has 35 problems. Each problem is worth either 5 points or 2 points. Let x = the number of questions worth 5 points. Let y = the number of questions worth 2 points. x+y = 35, 5x + 2y =100 How many problems of each point value are on the test? O 10 problems worth 5 points and 25 problems worth 2 points O 15 problems worth 5 points and 20 problems worth 2 points O 20 problems worth 5 points and 15 problems worth 2 points O 25 problems worth 5 points and 10 problems worth 2 points​

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

answer: 60%

explanation:

÷

= 60%

11) obtuse
