Answer:
z = 7
Step-by-step explanation:
9z + 4 / 5 - 8 = 5.4
Add 8 to both sides.
9z + 4 / 5 = 13.4
Multiply 5 by both sides.
9z + 4 = 67
Subtract 4 from both sides.
9z = 63
Divide both sides by 9.
7 (rounded up)
9z+4/5=13.5
Multiply both sides by 5
9z+4=67.5
Subtract both sides by 4
9z=63.5
Divide both sides by 9
z=7 (rounded up)
