14/4 or 7/2
Step-by-step explanation:
6 - (-7)
---------
-3 - (-7)
When you subtract a - its really just adding
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number
In this case a=5, and d=-2 so
a(n)=5-2(n-1) which can be simplified...
a(n)=5-2n+2
a(n)=7-2n
The domain is restricted to integers from 1 to +oo.
The answer is 58 pretty sure
6.5 times 4 and 13 times 2
D. Since you bought 3 text books you will have to multiply and then add the rest of the numbers
