l mass of the chemical in the container. What was the total mass in grams of the chemical in the container before the scientist removed the sample of 39.1 grams. show work please.
1. x3+x5=16. Multiply each side by 3: x+3x5=48. Continue simplifying and solving: 5x5+3x5=48. 8x5=48. 8x=240. x=30.
2. –7 x 8. –60. 3 ... You need to read the problem and know what information you (3 x 5) + (6 x 5) = (16 x 5) – (________ x 5(3 x 8) + ( ________ x 8) = 13 x 8
