Which statement describes a number with the smallest absolute value?
Snezhnost [94]
I believe C. The temperature is -23 degrees.

This is because, a negative (absolute value) becomes positive

Which would lead for |-23| to end up being |23|

Anytime a negative absolute value is placed, it becomes a positive and a positive stays positive.

So the smallest would be C then B later D and at last A

X=6 because
9-6=3

X=3 because
2•3=6

X=2 because
1.5 or 1 1/2 • 2 = 3

Answer:

a. 2.5  

b. 2.333

c. 2.85

Step-by-step explanation:

A) 1. subtract -x on both sides              2. to get 3x-1/2=7  

3. Add 1/2 on both sides                    4. to get 3x=7.5    

5. divide 3 on both sides                   6. To get... x=2.5

B)1. Same process.                               2. x+2=13/3        

3. x=13/3-2                                         4. x= 2.33(repeating)

C) 1. same process.                           2. 2x-x/3=3+7/4

3. 2x-x/3=4.75                                  4. Isolate -x/3  

5.-x/3=4.75-2x                                    6. multiply both sides by 3          

7. -x=14.25-6x                                      8. 5x=14.25

9. x= 2.85

* remember to distribute the 3 to each variable.
