Answer:
-1
Step-by-step explanation:
To find the slope of a line, we can do rise over run, or y/x.
r/r = 1/1 = 1
But as you can see, the line is going down which means it's decreasing, which means that it has a negative slope
slope = -1

Answer:
22
Step-by-step explanation:
If x = 5, then plug 5 in for x .
3(5) + 7
15 + 7 = 22
In the balanced reaction
2 Fe + O₂ → 2 FeO
2 moles of iron (Fe) react with 1 mole of molecular oxygen (O₂) to produce 2 moles of iron oxide (FeO). The ratio of Fe to FeO is 1-to-1, so if one starts with 42.4 mol of Fe, one will end up with the same amount of FeO, 42.4 mol.
Look up the molar mass of Fe and O:
• Fe = 55.845 g/mol
• O = 15.999 g/mol
Then the molar mass of FeO is approximately 71.835 g/mol, and so the mass of 42.4 mol of FeO is
(42.4 mol) × (71.835 g/mol) ≈ 3050 g
The answer is .008
Ok so lets explain this with an easier number like 1.
1 times 1/10 is 1/10 or in decimals its .1
So the decimal just got moved further back. Same thing happens with any number.

To know how to do this set up the question:
63/x = 60/100
63*100=60x
6300/60=x
x=105
