Answer:
1
Step-by-step explanation:
To multiply fractions, you multiply the numerator by the numerator and the denominator by the denominator. -8*-1 will turn positive because there are 2 negative signs, and will become 8. 1*8 is 8.
The fraction is now 8/8, which can be simplified to 1.
Therefore, 1 is the correct answer.
Answer:
D
Step-by-step explanation:
3/7 + 6/7 = 9/7
Change 9/7 to a mixed number = 1 2/7
Add your whole numbers: 1 + 10 + 1 = 12
Answer: 12 2/7
Answer:
x = +-sqrt(3) and they are the actual solutions
Step-by-step explanation:
x^2/ (2x-6) = 9/(6x-18)
get a common denominator of 6x-18
x^2/ (2x-6) * 3/3 = 9/(6x-18)
3x^2/ (6x-18) = 9/(6x-18)
since the denominators are the same, the numerators must be the same
3x^2 = 9
divide by 3 on each side
x^2 = 3
take the square root of each side
sqrt(x^2) = +-sqrt(3)
x = +-sqrt(3)
