Mr. martin is giving a math test next period. the test, which is worth 100 points, has 29 problems. each problem is worth either 5 points or 2 points . write a system of equations that can be used to find how many problems of each point value are on the test. let x be the number of questions worth 5 points and let y be the number of questions worth 2 points. how many problems of each point value are on the test?

The second option

Step-by-step explanation:

x+y=29

5x+2y=100

then y=29–x

since 5x+2y=100

then 5x+2(29–x)=100

then 5x+58–2x=100

then 3x+58=100

then 3x=100–58

then 3x=42

then x=42/3

then x=14

then y=29–14=15

207/8 is the right

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
