9x-30 I’m pretty sure!
We are finding the difference, which means subtract! Nine times a number would be 9x and since it’s difference you would subtract it by 30.
Answer:
$360
Step-by-step explanation:
If the company charges $30 for $500 in one month.
The interest they will be changing for a year = 30*12 = $360 interest.
It's just simple, multipling the the interest value by 12 to get it's annual interest value.
Answer:
35
Step-by-step explanation:
Alright this is like a linear pair. All three angles add up to 180; so this is the set up:
40 + 2x + 30 + 40 = 180
2x + 110 = 180
2x = 70
x=35
Answer: (C) the number of groups
Step-by-step explanation: It cannot be the total because the total is 18, the size of the groups does not make sense because it seems that you are trying to find a total, and the difference makes no sense because this does not seem like a subtraction problem. (C) the number of groups makes sense because their is a total number of groups.
Hope this helps! :)
