Answer:
15.31
Step-by-step explanation:
solve both sides separately
6x+78/67-78x
x cancles out
becomes 84/-11
becomes -7.64 rounded
180+270-567
becomes -117
moves -7.64 to other side (divide by other side)
-117/-7.64
becomes 15.31
Answer:
You had to pay $30.69 after the sales tax factored in.
Step-by-step explanation:
First step is to find 7% of $28.68.
The answer to that is the sales tax, therefore making the sales tax $2.01.
Finally, you have to add $2.01 to $28.68 to get a total of $30.69, your final answer.
Answer:
(x-9)(x²+9x+81); it'll give a difference of cubes
Step-by-step explanation:
Generally, the difference of cubes formula is (a³-b³)=(a-b)(a²+ab+b²), and the third option is the only one which fits it; with "a"= x and "b"= 9.
*The sum of cubes formula is (a³+b³)=(a+b)(a²-ab+b²); for future reference.
Answer:
a ≤ b + 5
a + b ≥ 40
2.5
a + 1.5
b ≤ 105
