Answer:
The son is five years old
Step-by-step explanation:
Let the son's age be x
A man is five as old as his son, 5x
In five years, he would be three times as old as his son
In five years: son would be x+5
Father 5x+5
3(x+5)=5x+5
3x+15=5x+5
Collect like terms
15-5=5x-3x
10=2x
Divide by 2
10/2=2x/2
x=5
The son is five years old
Answer:
-1 1/2
Step-by-step explanation:
-(3-6b)=6b + 5 .remember to balance!!!!
-6b + 6b= 6b + 6b
-3=12b+5
-3+5=5-5
-8=12b now divide since its the inverse operation
think 12/-8= -1 1/2
so B equals - 1 1/2
Answer:
The price elasticity of demand is 0
Step-by-step explanation:
The demand function for monthly sales is given as:
q = 104e^-3p^2 + p
The price elasticity of demand E is obtained by differentiating q with respect to p
E = dq/dp = (-6p + 1) × 104e^-3p^2 +p =
When p = ¥200
E = (-6×200 + 1) × 104e^-3(200)^2 + 200 = -1199 × 104(0) = -1199 × 0 = 0
