Solve -8|4b-6|+9=-39
LUCKY_DIMON [66]

Answer:

b=3                        b=0

Step-by-step explanation:

-8|4b-6|+9=-39

Subtract 9 from each side

-8|4b-6|+9-9=-39-9

-8 | 4b-6| = -48

Divide by -8

-8/-8 | 4b-6| = -48/-8

| 4b-6| = 6

When solving the absolute value, there is a positive and a negative solutions

4b-6  = 6      and 4b-6 = -6

Add 6 to each side

4b-6+6 =6+6     4b-6+6 = -6+6

4b =12                  4b = 0

Divide by 4

4b/4 =12/4            4b/4 = 0/4

b=3                        b=0

Formula = a = p* w

w (whole) = a/p

a/p = 80/0.20 (decimal form of 20%)

The initial weight was 400 pounds. It should be the answer so I hope this helps.
