Answer:
x = 11
Step-by-step explanation:
2(x - 5) = 12 ← divide both sides by 2
x - 5 = 6 ( add 5 to both sides )
x = 11

Answer:
Common Ratio = 2
Step-by-step explanation:
Emily started with 12 lb at start.
She will double each day
So,
2nd day she will take up weight = 12 * 2 = 24
3rd day she will take up weight = 24 * 2 = 48
and so on
This is a geometric sequence, which is a sequence where each term is found by multiplying the previous term by a constant which is known as the common ratio.
Here, we are multiplying by "2" to get the next term, so we an say the common ratio is "2".
<u>Answer: Common Ratio = 2</u>
Answer:
Arc EC = 58°
Step-by-step explanation:
First, find the value of x.
m<D = ½(arc EC) => Inscribed Angles Theorem
Substitute
2x - 5 = ½(5x - 27)
Multiply both sides by 2
2(2x - 5) = 5x - 27
4x - 10 = 5x - 27
Collect like terms
4x - 5x = 10 - 27
-x = -17
Divide both sides by -1
x = 17
Find arc EC:
Arc EC = 5x - 27
Plug in the value of x
Arc EC = 5(17) - 27 = 85 - 27
Arc EC = 58°
Im pretty sure its y= 5x-2
