Step-by-step explanation:
x = father's age now
y = son's age now
x = 2y + 10
x - 20 = 5(y - 20) = 5y - 100
using the first in the second equation :
2y + 10 - 20 = 5y - 100
-10 = 3y - 100
90 = 3y
y = 30
x = 2y + 10 = 2×30 + 10 = 60 + 10 = 70
the father is now 70 years old, the son now 30 years old.

Answer:
one number= x = 44
the other number= (x-4)= 40
Step-by-step explanation:
one number= x
the other number= (x-4)
x + (x-4) = 84
2x= 84+4
2x= 88
x= 88/2= 44
one number= x = 44
the other number= (x-4)= 40
20 cookies because y = 8 + 6(x)
X = 2 since half of the cookies left was 6
6(2) = 12 and 12+8 = 20
So in total she baked 20cookies
Answer:
Alternate exterior angles : ∠g = ∠b , ∠h = ∠a (opposite sides and on outer side)
Alternate interior angles : ∠c = ∠f , ∠e = ∠d (opposite sides and on inner side)
Consecutive interior angles : ∠c = ∠e , ∠d = ∠f (same sides and on same line)
Corresponding angles : ∠e = ∠a, ∠f = ∠b, ∠g = ∠c, ∠h = ∠d (same sides on the line)
Linear pairs : ∠c and ∠e, ∠d = ∠f, (they add to 180)
Vertical angles : ∠c =∠b, ∠d = ∠a, ∠g=∠f, ∠e = ∠h (vertical angles)
