Their frequencies are 1, 3, 2, 10, 2, and 1.
Add them together and you have 19 sloth sightings.
I think it would be 72+4x=400
400-72= 328
328/4= 82
So the answer would be 82=x
You combine both 2x-12 and x+2 and 11 which makes the equation
2x-12+x+2= 11
The you get your answer which is
X=7
Answer:
smallest triangle BCD
x = 15
Step-by-step explanation:
9/x = x/(16 + 9)
x² = 25(9)
x = ±15
