Answer:
B. 24
Step-by-step explanation:
Since both triangles are similar, therefore,
GM/XD = AG/KX
(x - 2)/6 = (x + 9)/9
Cross multiply
9(x - 2) = 6(x + 9)
9x - 18 = 6x + 54
Collect like terms
9x - 6x = 18 + 54
3x = 72
Divide both sides by 3
x = 72/3
x = 24
x = points in first game
y = points in second game
6x=y to make them equal multiply the first games points by 6
x+y=35 the points in both games
x +6x = 35 substitute for y (y=6x)
7x=35 combine like terms
x=5
y=6x
y=6(5)
y=30 points
11x-2
You combine same so
4x-1x =3x
3x +8x= 11x
11x-2
The answer is 3 because 4x6=24 and add 3 is 27 so she will need 3 dollars.
