Answer:

B. x < -11/3 or x > 7/3

Step-by-step explanation:

absolute value means

3x + 2 > 9 or -(3x + 2) > 9

for 3x + 2 > 9

3x > 9 - 2

3x > 7

x > 7 / 3

for -(3x + 2) > 9

-3x - 2 > 9

-3x > 9 + 2

-3x > 11

3x < -11

x < -11 / 3

65=91/?<br> What is the question mark

trapecia [35]

I would write the missing variable as x. It's what everyone uses.
Anyway, 91 divided by x is 65.
The way we can do this is reverse 65 and x.
91 divided by 65 = x.

91 divided by 1.4 = 65
65 x 1.4 = 91

x (or ?) = 1.4

Question 1. 7:11
Question 2. 27 units of K

How to solve the questions-
1. 14/22 divide the numerator and the denominator by 2. This would give you 7/11

2. If the ratio is 12/9 and the amount of N is 36, you’re basically multiplying 12 *3, so then you have to multiply 9 *3=27.
