A 40-question test has 108 possible points. There are m 4-point questions and n 2-point questions. How many of each type of questions are on the test?
m = 19, n = 21
m = 26, n = 14
m = 14. n = 26
m = 21, n = 19

answer is: m=14 , n=26

Explanation:

you multiply 14 × 4 and 26 ×2

you add the products which should get you 108

convergent boundaries: where two plates are colliding. subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.

divergent boundaries – where two plates are moving apart.

transform boundaries – where plates slide passed each other.

explanation:

i do agree with robert moses’ statements about wiping out cities that are an “impediment to new growth”. in order to have a positive community, the city must continue to grow either in terms of size or economics. therefore wiping out cities that restrict growth benefits the overall society and all the people living in it. similar to a social contract, i believe that if a person was to live in a community they must sacrifice some of their rights, in this case property, for the overall good of the people. as long as these people living in the cities are reimbursed and the purpose of wiping out the cities is to serve the public, there is no problem with robert moses’ core idea.
