tolong pake caranya plisss jawab dong yang tau

1. 3/x=6/10
x=3×10/6=5
2. x/2=6/4
x=2×6/4=3
.
y/10=6/10
y=10×6/10=6

5. x/3 = 6 + 4/4
= x/3 = 10/4
= 4x = 10×3
= x = 30/4
= x = 7,5 cm
6. x+EC/x = AD+BD/AD
x + 2/x = 6+4/6
x+2/x =10/6
6(x+2) = 10x
6x + 12 = 10x
10x - 6x = 12
4x = 12
x = 12/4
x = 3 cm
BC/y = AD+BD/AD
10/y = 6+4/6
10/y = 10/6
10y = 10×6
y = 60/10
y = 6 m
maaf klo salah
semoga membantu
