Answer:
![\sqrt[7]{b^{15}}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bb%5E%7B15%7D%7D)
Step-by-step explanation:
=> ![b^2*\sqrt[7]{b}](https://tex.z-dn.net/?f=b%5E2%2A%5Csqrt%5B7%5D%7Bb%7D)
=> 
Where bases are same, powers are to be added.
=> 
=> 
=> 
=>
= 11/12 - 1/6q + 5/6q - 1/3
to add like terms, we must first convert 1/3 to a common denominator with 11/12
= 11/12 - 1/6q + 5/6q - 4/12
combine like terms
= (-1/6q + 5/6q) + (11/12 - 4/12)
add/subtract inside each parentheses
= 4/6q + 7/12
simplify 4/6 by 2
= 2/3q + 7/12
ANSWER: 2/3q + 7/12
Hope this helps! :)
Anna's age is A
Courtney's age is C
A=2C+6
You get this because it says that Anna is twice Courtney's age so you multiply Courtney's age by 2. Then it says that she is 6 more which is why you add six after you multiply by 2.
So your equation is
A=2C+6
Hello from MrBillDoesMath!
Answer:
x = 1/2 (1 +\- i sqrt(23))
Discussion:
x \3x - 2 = (x/3)*x - 2 = (x^2)/3 - 2 (*)
1 \3x - 4 = (1/3)x - 4 (**)
(*) = (**) =>
(x^2)/3 -2 = (1/3)x - 4 => multiply both sides by 3
x^2 - 6 = x - 12 => subtract x from both sides
x^2 -x -6 = -12 => add 12 to both sides
x^2-x +6 = 0
Using the quadratic formula gives:
x = 1/2 (1 +\- i sqrt(23))
Thank you,
MrB
If one gallon is 21 miles, simply multiply 21 by five, for each of the five gallons and it is approximately 105 miles using 5 gallons of gas.
