Answer:
a) 10/3
Step-by-step explanation:
2x - 6 + 5x = 1/3 x - 9 + 2y
7x - 6 = 1/3 x - 9 + 2y
or
2y = 7x - 1/3 x - 6 + 9
2y = 21/3 x - 1/3 x + 3
2y = 20/3 x + 3
y = 20/6 x + 3/2
y = 10/3 x + 3/2
Y = mx + b where m = slope
In this case slope m = 10/3
Mitchell because if you add a zero at the end of the .8 it would be 0.80 and 0.75 is smaller than 0.80 so Mitchell has more work to do at home
2
The coefficient always comes before any unknowns, so for 2xy3, 2 is the coefficient.
It is a because 2/5 is more
According to the valence number of copper(2+) and the same value for chlorine (1-) copper (II) chloride has the formula of CuCl2
The molar mass of copper is 0,0635 kg/mole and chlorine gas a molar mass of 0,035 kg/mole the compound will have a molar mass of ( 0,0635+2×0,035 )kg/mole=0,099kg/mole and 0,344 moles are equivalent in mass to 0,344×0,135 kg=0,046 kg
