45=3*3*5, 63=3*3*7 The greatest common factor is the product of shared primes of the numbers prime factorization. In this case 3*3=9 is the product of shared primes so the greatest common factor is 9
Answer:
x = -12.5
Step-by-step explanation:
your goal is to get x alone so
-2x - 10 = 15

Step-by-step explanation:
If f = price of filing cabinet and c = price of cupboard we can make up the equation
2f + 4c = 800
we also know that f = 3c, so can substitute that into equation
2 (3c) + 4c = 800
6c + 4c = 800
10c = 800
c = 80
f = 240
