5(2x + 7) -3x = 7(x+5) one solution, infinitely many, or no solutions? help I'm on a timed math test this is my last one I have already tried doing it

How many different triangles can be constructed with the angle measurements of 134° 10° and 36° ?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Which of the following is the explicit rule for a geometric sequence defined a recursive formula of a -5a for which the first term is 23?
