The ratio of black cows to brown cows on a farm is 3:5. If there are 48 cows in all on the farm, how many are black?

there are 18 black cows

Step-by-step explanation:

ratio of black cows to brown cows=

3:5

Total number of cows=48

Sum of ratio=3+5=8

Number of black cows=3/8 x 48/1

Number of black cows=(3x48)➗8

Number of black cows=144 ➗ 8

Number of black cows=18

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
