Answer:
-3.8-22y
Step-by-step explanation:
3.2-11(2y+1)+4
-11×2y=-22y
-11×1=-11
3.2-22y-11+4
3.2-11+4=-3.8
-3.8-22y
Be careful you don't add unlike terms together (e.g. x^2 and x cannot be added or subtracted together).

The arc measure, which corresponds to the central angle measure, is always twice the subtended angle.
So 60 is twice a,
Answer: a=30
84 is twice b
Answer: b=42
60 + 100 is twice c,
Answer: c=80
d is what's left of the circle, total 360 degrees,
d = 360 - 84 - 60 - 100 = 116
Answer: d=116
Answer:
Eleana is 20 years old.
Her grandfather is 80 years old.
Step-by-step explanation:
Suppose Eleana's age is "x". That means her grandfathers age is 4x.
x+4x= 100
5x=100 Divide both sides by 5
x=20 That means Eleana is 20 years old.
Her grandfather would be 4 times her age so his age would be 40 years old.
