Simplify the following:
7 - 3 (9×2 n + (3 n + 8 n)/(-n))
3 n + 8 n = 11 n:
7 - 3 (9×2 n + (11 n)/(-n))
(11 n)/(-n) = n/n×11/(-1) = 11/(-1):
7 - 3 (9 2 n + 11/(-1))
Multiply numerator and denominator of 11/(-1) by -1:
7 - 3 (9 2 n + -11)
9×2 = 18:
7 - 3 (18 n - 11)
-3 (18 n - 11) = 33 - 54 n:
33 - 54 n + 7
Add like terms. 7 + 33 = 40:
40 - 54 n
Factor 2 out of 40 - 54 n:
Answer: 2 (20 - 27 n)
I havnt done this topic in maths for agesss but i can try and help. so overall there are 4 + 2 + 3 + 1, which is 10. so the probability that she will pick out a blue marble first is 4/10 i THINK. and the probability that she’ll pick out a yellow marble is 1/10.

Answer:
C. -7 < x < 7
Step-by-step explanation:
|2x| is the absolute value of 2x. You can think of it as the positive of a number, or as the distance between a number and 0 on a number line.
So |2x| < 14 means 2x is less than 14 units away from 0.
We can split this into two inequalities.
2x < 14 and 2x > -14
Solving both, we get:
x < 7 and x > -7
-7 < x < 7
