Farmer smith has 64 cows. 12 are white and the rest are black. what is the ratio of white to black cows?

3 : 13

Step-by-step explanation:

ratio of white : black cows is required

number of black cows = 64 - 12 = 52

white : black = 12 : 52 ( divide both parts of the ratio by 4 )

                     = 3 : 13 ← in simplest form

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
