Your math test is worth 100 points and has 38 problems. Each problem is worth either 5 points or 2 points. How many problems of each are on the test? Let x = number of 5 point problems. Let y = number of 2 point problems. a) Equation 1 can represent the number of problems on the test and can be modeled as such: # of 5 point problems + # of 2 point problems = total number of problems. Write this as an equation: Equation 1: b) Equation 2 can represent the points per question and the total which can be modeled as such: 5 point problems + 2 point problems = total points. Write this as an equation: Equation 2: c) Complete the statement using the solution to the system: There are 5 point questions on the test, and 2 point questions on the test.

b

step-by-step explanation:

what? that isnt a question

step-by-step explanation:

answer: it is 8

step-by-step explanation:

you know why its 8

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
