Help solving the following Lcm of 6, 3, and 5?

30

Step-by-step explanation:

(This is only a good method for small numbers) multiples of 6:

6 12 18 24 30 36

now check one by one if 3 and 5 divide by them

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

y/x of point b= y/x of point a
