Answer:
Step-by-step explanation:
The required answer is the rate at which Machine A works when the two machines are combined.
Note: the rate of doing work is express as
Hence we can conclude that Machine A working rate is
and machine B working rate is
When the two machine works together, the effective working rate is
The fraction of the work that Machine B will not have complete because of Machine A help is the total work done by machine A
Hence the fraction of work done by A is expressed as
Hence the fraction of the work that Machine B will not have complete because of Machine A help is the total work done by machine A is
The distributive property: a(b + c) = ab +ac
-7(8x - 3) + x = -7· 8x - 7 · (-3) + x = -56x + 21 + x = (-56x + x) + 21 = -55x + 21
Answer: x>−50
Step-by-step explanation:
Distribute
4x-48-3<5x-5+4
4x-51<5x-1
Subtract 5x from both sides
-1x-51<-1
Subtract 51 from both sides
-1x<50
Answer:
1.8611 x 10^4 lbs per capita
Step-by-step explanation:
To calculate the per capita garbage we have to divide the amount of garbage by the number of people
garbage = 5.416 x 10^12 lbs
people = 2.91 x 10^8
5.416 x 10^12 / 2.91 x 10^8 =
To make it easier we can take the scientific notation of the first term to the same exponent the second
5.416 x 10^12 = 54,160 x 10^8
54,160 x 10^8 / 2.91 x 10^8 =
Now that we have multiplying the same in both parts of the division you can simplify both terms above and below
54,160/2.91 = 18,611
18,611 = 1.8611 x 10^4
