The answer would me 4.33 if you do it on a calculator
Here is part of it I’ll send the other part now
X=5/2,x=2
i cant explain it but if you got to symbolab.com and input the equation it will solve and show you the steps
Answer:
x=-1
Step-by-step explanation:
-3x=-10+13 - -3x=3 - -3 = -1
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
