Where the heck did x come from!
Answer:
1,311
Step-by-step explanation:
Standard form: x-y = -3
x & y have to be whole numbers
x has to be positive
3z - 12 = 63
+ 12 +12
3z = 75
z = 25
x + 63 = 180
- 63 - 63
x = 117°
The unit rate for $240 per 4 days is $60 per 1 day.
To get a unit rate you must simplify the rate down to $X per 1 day.
To get 4 days down to 1 day you must divide 4 by 4.
Doing the same to the other side you divide 240 by 4.
So now you have $60 per 1 day.
