Answer:
17
Step-by-step explanation:
So the equation would be c=12 so 12+5 would equal, 17. Dduen guem po right.
9,2.5,-4,-10.5,-17
Let's find the difference between two consecutive terms
2.5 - 9 = -6.5
-4 - 2.5 = -6.5
-10.5 - (-4) = -6.5
-17 -(-10.5) = -6.5
We can see that the common difference is -6.5
-6.5 is the common difference between successive terms in the sequence 9,2.5,-4,-10.5,-17
the common difference is negative because we subtract 6.5 to get the next term.
Answer: 12 refills
Step-by-step explanation:
y = 8.95 + 1.50x
26.95= 8.95 + 1.50x
26.95 - 8.95 = 1.50x
18 = 1.50X
18 / 1.50 = x
X = 12

The complete Question is attached below
Answer:
we know that sum of angle a and b is 180
so a+b= 180
a= 34 (given)
b= 180-34
b= 146 degrees
