it is either 32.48 or 14.1. I d k if to add or multiply.

Step-by-step explanation:

Have a great day! I hope this some what helped you

2x+1=10    2x=9    x=9/2
-2x-1=10     -2x=11    x=-11/2

The answer is C

A

Step-by-step explanation: i just redid the test on edge

a

Step-by-step explanation:

Answer is A. 4,10,8,6

the mean is 7. A is the most clustered around 7

the correct answer is a

PLS MARK BRAINLIEST

Step-by-step explanation:

x = -1

12

Step-by-step explanation:

12x + 11 = 10

-11

12x = 10 - 11

12x = -1

÷12

x = -1 ÷ 12

x = -1

12

i don't know if this is right because it's not one of your answers..??

By definition of absolute value we have two equalities:
 2x + 1 = 10
 2x + 1 = -10
 For 2x + 1 = 10:
 2x + 1 = 10
 2x = 10-1
 2x = 9
 x = 9/2
 For 2x + 1 = -10:
 2x + 1 = -10
 2x = -10-1
 2x = -11
 x = -11 / 2
 
 {-11/2, 9/2}

The answer is -11/2, 9/2

Explanation

You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10

Then you solve for X in each equation.
2x+1=10 would give you 9/2

2x+1=-10 would give you -11/2

So your final solutions would be x1= -11/2 x2= 9/2
