Answer:
x = 13.
So the 3 angles are a = 44, b = 47 and c = 89 degrees.
Step-by-step explanation:
If these are the angles are the 3 angles of a triangle they sum to 180 degrees, so:
3x + 5 + 5x - 18 + 7x - 2 = 180
15x - 15 = 180
15x = 195
x = 195/15
x = 13.
Answer:
a(n) = 1(2.5)^(n - 1)
Step-by-step explanation:
The geometric sequence is 1, 2.5, 6.25, 15.625, and so on; the first term is 1. The common ratio is 2.5; each new term is 2.5 times the previous term.
The explicit formula desired is thus a(n) = 1(2.5)^(n - 1)
Answer: 3000 + 900 + 60 + 1
Answer:
slope is 0
Step-by-step explanation:
The slope of any horizontal line is zero, 0.
Hi,
Start with 6b-27=3(5b-2)
then add 27 to each side, 6b-27+27=15b-6+27
next simplify, 6b=15b+21
now subtract 15b from both sides, 6b-15b=15b+21-15b
simplify again, -9b=21
divide both sides by -9, -9b/-9 = 21/-9
answer: -7/3
Have a great day!
