Answer:
x>9
Step-by-step explanation:
-4x + 15 < -21
Subtract 15 from each side
-4x + 15-15 < -21-15
-4x < -36
Divide each side by -4, remembering to flip the inequality
-4x/-4> -36/-4
x >9
First do 8 divided by 9 = 0.88 x 6 x 19 start from the left and work to the right 0.88 x 6 = 5.33 x 19 = 101.3
