Answer:
500
Step-by-step explanation:
Convert percent to decimal:
94%=
100
94
=0.94
Move decimal 2 places to the left
Multiplying the decimal by the whole gives us the part:
0.94x=
0.94x=
470
0.94
0.94x = 0.94
470
Divide both sides by 0.94x=
500
Answer:
His collection increased in a 20%.
Step-by-step explanation:
If 100% represents 10 records, what percentage would be for 12 records?
x = 12 100% / 10 = 120%
So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.
F(x)=2x-10
y=2x-10
x=2y-10
x+10=2y-10+10 (add both sides by 10)
2y=x+10
2y/2=x+10/2 (divide both sides by 2)
y=1/2x+5
Final Answer: f^-1(x)=1/2x+5
50% - .5
7/15 - .46
