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

Ill give you brainliest>>>Write an equation of the line passing through the point (5, 2) that is perpendicular to the l
11Alexandr11 [23.1K]

y= mx+b

(16, -7) = (x,y)

2(16) - 3y = 12

32 - 3y = 12

32 - 12 = 3y

20/3 = y

6.6 = y

2x-3(-7) = 12

2x+21 = 12

2x = 12 - 21

x = -9/2

Insert the values into y = mx + b

solve for m and then solve for b
