solve each equation: if the equation has no solution, write no solution by the way / means its a fraction 1) x+4/5 = x+5/7 2) x/x-5 = -2x/x 3) 4.5/x= 8-x/x-8 4) If a gas was in a 7.5 liter flexible container under 4 atmospheres of pressure, how would the volume of the gas change and what would it be if the pressure was increased to 6.5 atmospheres, keeping all other variables constant? 5) given the formula V=1/3Ah, solve for h pleaaaaase help me (: if you dont know all of them its ok just tell me whatever you know. thank you soooo much
