Answer:
I think 2 but sorry if I'm wrong
Step-by-step explanation:
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:
<h2>17/35</h2>
Step-by-step explanation:
We need to get all the fractions with a common denominator before we can solve the problem.
The only fractions that have a common multiple are 1/7 and 3/21, so we'll add these first and then add 1/5.
1/7 = 3/21
Add

6/21 = 30/105
1/5 = 21/105

Simplify

ANSWER: 17/35</h3>
I'm always happy to help :)
Area = 4.5 x 4.5 = 20.25 in²
Perimeter = 4 x 4.5 = 18 in
First multiply 57 x 30, then 30 x .35, then Ta da you have your answer (which is 598.5)
