Find use the distributive property and bring down the ending result (21)
-3x-6=21

Next, add 6 on both sides and you should get:
-3x = 27

The last step is, you divide -3 from 27 and you end up with 9. So, the total answer is x = 9

Find the area of a 120° sector of a circle whose radius is 6.
katrin [286]
First, determine the area of the whole circle by the equation, A = πr². Substituting,
                             A = π(6²) = 36π
Then, multiply this value with the ratio of the given angle to the whole revolution,
                            A(sector) = 36π x (120° / 360°)
The area of the sector is therefore 12π units².

sveticcg [70]
Yes and no. A negative number and it's opposite are 'integers.' Yes, a negative and a negative multiplied together give you a positive. The two negative signs cancel out making it positive. But no, a positive and a positive multiplied together do not give you a negative. When you subtract positive numbers you can get a negative, but not when multiplying. If you were to do a positive times a negative it would be negative because the positive can't cancel it out. Example: -3 · -3 = 9. [] 3 · 3 = 9. [] -3 · 3 = -9. Other than the positive number part, the statement is true about the negatives. I hope that helped!

What is 3k +2 ( 5k - 3) = 7
polet [3.4K]

Answer:

k= -0.2

Step-by-step explanation:

3+2(5k-3)=7              (original)

3+10k-6=7                 (distribute 2 in (5k-3))

9+10k=7                    (combine like terms 3+-6)

10k=-2                       (subtract 9 on both sides to isolate k)

k=-0.2                       (divide 10 on both sides to get you're answer/isolate k)
