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
3y - 1 = 28
+ 1 + 1

Answer:
120
Step-by-step explanation:
3/8 3*8=24, 24+3 = 27
5/12 5*12 =60 60÷5= 65
27 + 65 = 92
212-212- 92=120
Answer:
simple interest :90
Step-by-step explanation:
Step 1: Multiply 450 with the interest rate which is 0.05 so that equal 22.5
Step 2: Multiply the 22.5 with the 4 years
So Multiply principal with the interest rate with the time
