Answer:
x= 14 y= 13
Step-by-step explanation:
Use substitution or elimination
Answer:
Angie=x
Susan = x+3
Rebecca = 3(x+3)
Total = 5x+12
If Angie has 4 then the total is 32
Step-by-step explanation:
Angie has x games
Susan has 3 more games than Angie has
Susan = x+3
Rebecca has 3 times more games than Susan
Rebecca = 3Susan
We know Susan has x+3 so replacing it in
Rebecca = 3 (x+3)
The total number of games is Angie + Susan + Rebecca
x + x+3 + 3(x+3)
Distributing the 3
x + x+3 + 3x+9
Combining like terms
5x+12
The total number of games is
5x+12
If Angie has 4 games, x=4
The total number of games is 5(x)+12
5*4+12
20+12
32
Perimeter is the sum of the sides.
4x + 6 +3x + 2 = 57
7x + 8 = 57
7x = 49
x = 7
