6x-12=2x-6 Also,how do you check your answer?

1 answer:

7 0

6x-12 = 2x-6

get like terms on the same side by adding/subtracting.

6x - 12 = 2x - 6
+ 12, -2x on both sides

6x - 2x = -6 + 12

4x = 6

divide all by 4

x = 1.5

to check your answer, plug in 1.5 for x and see if they are equal to one another.

6(1.5) - 12 = -3
2(1.5) - 6 = -3

denis-greek [22]

Answer:

Option B

Step-by-step explanation:

Here we have to apply " combination and permutation. " It is given that the drama club had to choose three booths from a selection of 9, considering the possible ways to choose so. This is a perfect example of combination. In nCr, n corresponds to 9, respectively r corresponds to 3.

$\mathrm{n\:choose\:r},\\nCr=\frac{n!}{r!\left(n-r\right)!},\\\\\frac{9!}{3!\left(9-3\right)!} =\\\frac{9!}{3!\cdot \:6!} =\\\\\frac{9\cdot \:8\cdot \:7}{3!} =\\\frac{504}{6} =\\\\84\\\\Solution = Option B$
