Andell is 9 years older than Arnez. arnez is 3 years younger than Marianne. the sum of their ages is 24. what is the age of each
Harman [31]

Answer:

Arnez is 4. Andell is 13. Marianne is 7.

Step-by-step explanation:

Let x represent Arnez's age. If we write out an equation, we end up with this:

24 = (9 + x) + (x + 3) + x

24 = 9 + x + x + 3 + x

24 = (x + x + x) + (9 + 3)

24 = 3x + 12

24 - 12 = 3x + 12 - 12

12 / 3 = 3x / 3

4 = x

Antonio has more money than Dominic . if Antonio gives Dominic $18 then they'll have the same amount . If Antonio gives Dominic.
Simora [160]
Let x be the money Antonio has. 
Let y be the money Dominic has. 

x-18=y (here, I just put in the equation) 

Since we are not given any information about the money that Dominic has or Antonio has, we would have to create an equation that would fit all the situations. 

Hope I helped :) <span />
