Hey I need help with these questions.

IN UIRY /12 0.4; Salt water is owing into a large tank that contains pure water. The concentration of salt c in the tank at t minutes is given by c(t)=10t/(25+t), where c is measured in grams per litre. When does the salt concentration in the tank reach 3.75g/l 4 Q5; Solve and check 2x 2x 2x+3_ 2x-3 =1 4 Q.6:Determine the solution set for the inequality (x+3)/(x+l)Z(x-2)a'(x-3) 4 COMMUNICATION ['8 Q6; Sketch the graph of the special function 4 g(xHx-4)I(x2+x2o) 0.7; Solve the inequality, illustrate the solution on a number line. 4 (2/X)+3>(29/x)
