4^x=2×2^x=2×7=14
4^x-1=14-1=13
Since a percentage is out of 100, simply divide 1.147 by 100 to get a percent. Dividing by 100 means moving the decimal two please to the left(once for each 0). So we should have 0.01147%
Answer:
72.2%
Step-by-step explanation:
Given data
Initial price= £245
Final price= £883
% increase= Final - Initial / final *100
% increase=883 - 245 / 245 *100
% increase= 638 / 883 *100
% increase=0.722*100
% increase=72.2%
Hence the increase is 72.2%
Answer:
Step-by-step explanation:
Unfortunately, your " 12×+9=10×1 " can be interpreted in more than one way. The symbol " × " should be used ONLY to indicate multiplication. Thus, " 12× " reads as ' 12x.' Then we have: 12x + 9 = 10. Unsure of what you meant by " 10×1". So I will treat your "10×1" as simply '10.'
Then we have 12x + 9 = 10, which reduces to 12x = 1 if we subtract 9 from both sides.
12x = 1 yields x = 1/12.
If this is not the result you expected, please go back to the original problem and share it as accurately as you can.
