The equation |–x – 4| = 8 will have two solutions. the equation 3.4|0.5x – 42.1| = –20.6 will have one solution. the equation startabsolutevalue startfraction one-half endfraction x minus startfraction 3 over 4 endfraction endabsolutevalue equals 0. = 0 will have no solutions. the equation |2x – 10| = –20 will have two solutions. the equation |0.5x – 0.75| + 4.6 = 0.25 will have no solutions. the equation startabsolutevalue startfraction 1 over 8 endfraction x minus 1. endabsolutevalue equals 5. = 5 will have infinitely many solutions.

i am unable to solve this problem

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
