Look at deonomators
assuming that the deonomenators are 5x+15y and 2x+6y
find their LCM
factor
5x+15y=5(x+3y)
2x+6y=2(x+3y)
LCM=10(x+3y)=10x+30y
multiply 2/(5x+15y) by 2/2=4/(10x+30y)
multiply 1/(2x+6y) by 5/5=5/(10x+30y)
if we add them
9/(10x+30y)
10x+32=0
10x=-32
x=-32/10 or -3.2 or -16/5
1. Reflect over x axis, right 1, up 8
2. Ref. over x, stretch 4 (up and down), up 6
3. Stretch 2 (side to side), left 9, down 5
4. stretch 8 ( s to s), reflect over y, down 4
5. Ref. over x, stretch 2/7 (s to s), up 5
Answer:
500,000km
Step-by-step explanation:
Scale: 1cm:50000km
10 cm = 50000*10km
10 cm = 500000km
