Roberto solved the following equation as shown. On which step did he apply the commutative property of addition as justification?
8+5(x - 3) = 23
Step 1: 8 + 52 - 15 = 23
Step 2: 5x + 8 - 15 = 23
Step 3: 52 - 7 = 23
Step 4: 52 = 30
Step 5: x = 6

1. minimum

2. 6400

3. eight

hope this !

30005

yes ok                                            

your answer is -9

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
