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

Answer:
Step-by-step explanation:
Looking at the diagram,
Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that
DH/DB = TH/MH
DH = 15 + 6 = 21
TH = 9 + x
Therefore
(9 + x)/21 = 9/6
Cross multiplying, it becomes
6(9 + x) = 21 × 9 = 189
54 + 6x = 189
Subtracting 54 from the left hand side and the right hand side of the equation, it becomes
6x + 54 - 54 = 189 - 54
6x = 135
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 135/6
x = 22.5
