Pqrs is a rhombus, with diagonal pr

and the following measurements:

m∠spr=(3x + 12)∘

m∠qpr=(4x−6)∘

what is the measure of ∠spq
in this rhombus?

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.
