Your math class is collecting canned food for a local food drive. The goal is to collect at least 110 cans but no more than 190 cans due to space limitations. There are 20 students in your math class and your teacher has promised to bring in 10 cans. Select which inequalities represent the possible numbers n of cans that each student should bring in.

9<190

Step-by-step explanation:

The teacher is supposed to bring in 10. so 190-10 would be 180. 180/20=9. Each student can bring a max number of 9.

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
