Answer:
positive 12/5
Step-by-step explanation:
First distribute: -12m - 20 = -2m + 4
Add like terms: 10m - 20 = 4
Isolate variable: 10m = 24
Divide: 2.4 or 12/5
everything can be found in the picture
63.6
(x+4)
in this problem we have
2,350 million
Remember that
1 million=1,000,000
so
2,350 million=2,350*1,000,000=2,350,000,000
convert to standard form
2,350,000,000=2.35*10^{9}
therefore
the answer is
2.35*10^{9}
