Answer:
4b^4 + 6b^3 + 13b^2 + 10b -1
Step-by-step explanation:
4b^4 + 12b^3 + 5b^2 + 6 - (6b^3 – 8b^2 – 10b + 7)
= 4b^4 + 12b^3 + 5b^2 + 6 - 6b^3 + 8b^2 + 10b - 7
= 4b^4 + ( 12b^3 - 6b^3) + (5b^2 + 8b^2) + 10b + (6 - 7)
= 4b^4 + 6b^3 + 13b^2 + 10b -1
Answer and Step-by-step explanation:
Suppose x = 0.2355555... .
Multiply x by 100 and 1000:
100x = 23.5555....
1000x = 235.5555....
Let's subtract the first equation from the second:
1000x - 100x = 235.5555.... - 23.555.....
Because the decimal part for each goes on forever, we can simply cancel them out in our subtraction statement:
900x = 235 - 23 = 212
Divide both sides by 900:
x = 212/900 = 53/225
Thus, since x = 0.235555..., we know that:
0.23555.... = 53/225
Since p = 53 and q = 225 are integers, we have proven that this repeating decimal can be written as a fraction.

Answer:
$50
Step-by-step explanation:
If the tip was $9, you can find the total price by <u>dividing</u> 9 by .18. .18 is 18% but as a decimal (move to the left two decimal places). 9/.18 = 50.
You can also check the answer by finding the 18% tip of $50. 50*.18=9.
