Answer:
The mass of the grains = 120 ± 1 g
Step-by-step explanation:
we are given the following:
Total mass of container + grains = 185 grams
Mass of container = 65 grams
Therefore, mass of grains is calculated as follows:
Mass of grains = ( Mass of container + grains) - mass of container
= 185 - 65 = 120 grams.
since the scale has an absolute uncertainty of 1 g, the mass of the grains is written as 120 ± 1 g
Answer:
Step-by-step explanation:
to find out, just sub in -8 for x and find out if it is true
3x = 16 - 5x
3(-8) = 16 - 5(-8)
-24 = 16 + 40
-24 ≠ 56......no, -8 is not a solution
3x = 16 - 5x
3x + 5x = 16
8x = 16
x = 16/8
x = 2 ............2 is the correct answer
The 1 is viubel so it will be 1f
