Total amount = 1 x 10 + 3 x 5 = $25
Amount spent = $9.30 + $4.20 = $13.50
Amount left = $25 - $13.50 = $11.50
Answer: $11.50
Answer:
53,760,970 households/year
Step-by-step explanation:
First step is to do 65,929,420 - 12,168,450 = 53,760,970
Now divide 53,760,970 by 20 since the difference in 1997 and 1977 is 20
53,760,970/20 = 2,688,048.5
So each year 2,688,048.5 people got cable.
But it would be 53,760,970/year because then you could divide it by how ever many years to see how many people got cable.
Hope this helps!!
5) the yearly rate is 5 million $
6) 70 million $
Answer:
3+5n=5(n+2)-7*
We move all terms to the left:
3+5n-(5(n+2)-7*)=0
We calculate terms in parentheses: -(5(n+2)-7*), so:
5(n+2)-7*
We add all the numbers together, and all the variables
5(n+2)
We multiply parentheses
5n+10
Back to the equation:
-(5n+10)
We get rid of parentheses
5n-5n-10+3=0
We add all the numbers together, and all the variables
-7!=0
There is no solution for this equation
Step-by-step explanation:
Answer:
x = ln 10
Step-by-step explanation:
You meant e^x - 1 = 9. Let's isolate e^x, by adding 1 to both sides. We get:
e^x = 10
Now make use of the property ln a = b <=> a = e^b
Then e^x = 10 becomes
x = ln 10
