Ayy you got it right thank you very much your
Answer:
1x
Step-by-step explanation:
12x-9= 3x.
1/3 of 3 is 1.
So therefore the answer is 1x.
-12/-9=y/-4
cross multiply
-9y=48
divide by 9 on each side
y= -5.33
Step-by-step explanation:
this is the answer key for that question and etc...
Sqrt(486) - sqrt(24) + sqrt(6)
find the factors of 486 that we can remove from under the square root sign
2 * 243
2 * 3 * 81
2 * 3 * 9 * 9 (we have 2 nines, we can move a 9 outside the sqrt sign)
sqrt(486) = 9 sqrt(6)
Repeating for sqrt(24)
2 * 12
2 * 2 * 6
2 * 2 * 2 * 3 (we can move a 2 outside the sqrt
sqrt(24) = 2 sqrt(6)
Finally, add all 3 terms together
9 sqrt(6) - 2 sqrt(6) + sqrt(6)
8 sqrt(6)
8 times square root of 6 is the final answer
