Answer:
9
Step-by-step explanation:
Use PEMDAS to solve it.
2 3 - (8-4) + 5 =
First: 2 3 - (4) + 5 =
Second: solve the 2 to the power of 3 exponent
2×2×2=8 (2×2=4 then 4×2=8)
So, 8 - 4 + 5 =
Third: 4 + 5 =
Last: 9
Answer:
nth term = 18 - 3n
Step-by-step explanation:
nth term = a + (n - 1)d
a1 = 15
d = -3
nth term = a + (n - 1)d
= 15 + (n - 1)-3
= 15 + (-3n + 3)
= 15 - 3n + 3
= 18 - 3n
nth term = 18 - 3n
For instance, if you want to find the 10th term
nth term = 18 - 3n
10th term = 18 - 3(10)
= 18 - 30
= -12
10th term = -12
Angles that combine to make a straight line add up to __180__ degrees.
I hope this helps! :)
