Answer:
Dan is 25 years old.
Step-by-step explanation:
1. Find out Dan's age from 8 years ago: 14 - 8 = 6
2. Find out how old Marge was: 6 ÷ 2 = 3
3. Add 8 years to Marge's age to find out how old she is now: 3 + 8 = 11
4. Add 14 years to Marge's age now to find out Dan's age now: 11 + 14 = 25
∴ Dan is 25 years old
x + 7x = 56 + 8
Simplifying
x + 7x = 56 + 8
Combine like terms: x + 7x = 8x
8x = 56 + 8
Combine like terms: 56 + 8 = 64
8x = 64
Solving
8x = 64
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '8'.
x = 8
Simplifying
x = 8
Hope this helps, and I hope this is the answer!
8x + By + 92 = 0
(-4; 12) ⇒ x = -4; y = 12
subtitute
8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0 |subtract 60 from both sides
12B = -60 |divide both sides by 12
B = -5
