Answer:
$25.75
Step-by-step explanation:
$30.00 - $4.25 = $25.75
X=2n+1 x=6 n=4
6=2 times 4 +1=9
6=9 and since 18 divided by 6=3, then n=9 times 3 which equals to 27
n=27
First determine how many push-ups he does each time
2 sets × 25 pushups = 50 pushups
Now times that by the number of times he does this each month
50 pushups × 10times a month = 500 pushups a month
The answer is A.
2 x -3 = -6
3 x 3 = 9
now add those up
-6+9=3
