I will assume that by "Evaluate 8(7x--3) when x=9" you meant:
"Evaluate 8(7x-3) when x=9."
First, substitute 9 for x in 7x-3: 7(9)-3 = 60. Rewrite the problem as:
8(60). Multiply. Answer: 480
Answer:
If not simplified 35/8 if simplified 4 and 3/8.
Have a fantastic day :)
You can either round to 1000 or 2000 but 1.120 is closer to 1000
