you need to find 30% of 560.
1.) first, you must do 560 times 30%. turn 30% into a simplified fraction by putting 30 over 100. you can simplify 30/100 to 3/10.
2.) next, multiply 560 by 3/10, which equals 168.
put equation (2) to equation (1)
-2y+1 + 2y=9
-2y + 2y=9-1
we have the formula:
take the numbers 50 and 30. their greatest common factor is 10, since 10 is the greatest factor that both numbers have in common. to find the gcf of greater numbers, you can factor each number to find their prime factors, identify the prime factors they have in common, and then multiply those together.
