Answer:
y=4x+25
Step-by-step explanation:
y-11=4(x+8)
y-11=4x+36
y=4x+25
Let s represent the measure of the second angle.
The measure of the first angle is 15° less than the second, so we can represent the first angle by (s-15).
The measure of the third angle is 45° more than half the second, so we can represent the third angle by (45+(s/2)).
The sum of these angles is 180°, so we can represent the sum as
... (s-15) + s + (45+s/2) = 180
Collecting terms, we have
... 2.5s +30 = 180
... 2.5s = 150 . . . . . . subtract 30
... s = 150/2.5 = 60 . . . . divide by the coefficient of s
The first angle is 60-15 = 45.
The second angle is 60.
The third angle is 45+60/2 = 75.

The sum of the three angles is 45 +60 +75 = 180.
Hello from MrBillDoesMath!
Answer: 1/2
Discussion:
Note that:
16 /2 = 8 (the next term in the sequence)
8 /2 = 4 (the next term in the sequence)
4 /2 = 2 (the next term in the sequence)
We are repeatedly multiplying by 1/2
Thank you,
MrB
