7 + 7 + 7 + 7 = 30
7 repeats itself 4 times to equal 30
There is no b unfortunately
Find inverse of x+a
interchAnge
Inverse is
Now
- x-a=cx-d
- x-cx=a-d
- x(1-c)=a-d
- x=a-d/1-c
So
You can have any number according to this but
- c must not be 1
- a and d must not be equal .
- All three should belongs to integers set
Note:-
As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also
Answer:
-7d
Step-by-step explanation:
42 divided by -6 =7d
B = 100(1 + 0.04)^12 = 100(1.04)^12 = 100(1.601) = $160.10
