Answer:
$46.72
Step-by-step explanation:
The first step is to find the price of 1 gallon
5 gallons= 14.46
1 gallon= x
5x= 14.46
x= 14.46/5
1 gallon= $2.92
Therefore the cost of 16 gallons of gasoline can be calculated as follows
1 gallon= 2.92
16= x
x= 2.92 × 16
= $46.72
Answer:
Pool will be filled in 280 hours
Step-by-step explanation:
Inlet pipe fills in 40 hours = 1 pool
Inlet pipe fills in 1 hours = 
Drain pipe empty in 42 hours = 1 pool
Drain pipe empty in 1 hour = 
If both pipes are opened together
then in pool fills in 1 hour = -
on simplifying the right side ,we get 
= 
= 
pool fills in 1 hour
1 pool will be filled in 840 hours
pool is filled
empty pool = 1 - = 
therfore pool will be filled in X 840 =
= 280 hours
Step-by-step explanation:
Average=total numbers of songs /registered users
Average= 4*10^9/5*10^7
Average=40*10^8/5*10^7
Average=8*10^(8-7)
Average=8*10^(1)
Average=80 songs downloaded per user
Answer:
3
Step-by-step explanation:
Firstly, do the numbers inside the absolute value bars.
-6-(-3)
The two negatives that are together turn to a addition sign.
-6+3
You can just subtract 6 and 3 which is 3 and add the - to it.
|-3|
The -3 turns to a 3 since the absolute value bars make all numbers positive within the bars.
Hope this helped.
First, open the parentheses (make sure you distribute the '-':
6x - 3x - 4 = x - 40
3x - 4 = x - 40
2x = -36
x = -18
The solution set is {-18}
