You do it like this:
15/100 = 21/x and cross multiply like this:
15x = 2100 ((Divide by 15 on both sides)
x = 140 (This is your answer)
I hope this helps you! Have a great night!
Answer:
B) 9
Step-by-step explanation:
We want to find how many nests had more than 4 eggs. That would mean how many nests had 5 6 or 7 eggs
There are 6 nests that had 5 eggs, 2 nests that had 6 eggs and 1 nest that had 7 eggs
6 + 2 +1 = 9 nests that had more than 4 eggs
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
So Andrew is 4 years old
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
You already have the equation! If you want it in vertex form, do this:
y = x^2 + 8x + 16 - 16 - 51, or y = x^2 + 8x + 16 -67, or
y = (x+4)^2 - 67.
The vertex is at (-4,67).
