(3, 4)
Answer:
25
Step-by-step explanation:
Answer: x = 27
Step-by-step explanation:
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)
Answer:
210
Step-by-step explanation:
10+10+1=21
21 x 10=210
