a.) you start with 19=h/3-8 so you add 8 to both sides then you simplify 19+8 to 27 so the equation then becomes 27=h/3 from there you multiply each side by 3 so its 27*3=h then you simplify 27*3 which leaves you with 81=h u then switch it around and your final answer h=81
b.) you start with 0.6x +0.8=1.4 first you subtract 0.8 from both sides so the equation is 0.6x=1.4-0.8 then you simplify 1.4-0.8/ so it then becomes 0.6x=0.6 u then divide both sides by 0.6 so the equation is now x=0.6/0.6 you then simplify 0.6/0.6 so you are left with x=1
I’m pretty sure the answer is 160 because the rectangle on the top has a volume of 64(16 x 4) and the rectangle on the bottom has a volume of 96(2 x 4 x 12). Add those together and you get 160 cubed inches. Hope this helped :)
