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 
Answer:

Step-by-step explanation:
We can use properties of exponents to solve these equations. Remember that when multiplying exponents, we 'add' them.

For the next question:

These are your answers!
2x - 3 = 8
add 3 to both sides
2x = 11
divide both sides by 2
x = 5.5
