What value of x makes this equation true?
0.3x-7=0.8x+15
a. 52
b. -44
c. -16
d. 6

B. -44

Step-by-step explanation:

0.3x-7=0.8x+15

first subtract 0.3x to the other side of 0.8x which will equal

-7=0.5x+15

Then subtract 15 to the othe side of the equal sign which will be

-22=0.5x

Then divide both sides of 0.5( use calculator and put in -22/0.5)

which will be -44

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
