Plzz hurry i only have 20 minutes which equations have the same value of x as 3/5(30x-15)=72 check all that apply? ? 18x-15=72 50x-25=72 18x-9=72 3(6x-3)=72 18x-81 18x=63 x=3.5 x=4.5

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

The triangles in the diagram are congruent. if mzf = 40°, mza = 80°, and mzg = 60°, what is mzb?
