Answer: see image attached
y<x/2+6 is the yellowish area (with dashed boundary as that does not belong to the solution space)
x+3y>=12 is rearranged as y>=-x/3+4 and solutions correspond to the bluish shaded area (with solid line, due to the equal sign)
The solutions satisfying both inequalities are in the overlap area of the two.
The answer is B, kilometers.
—Evidence—
•] it is assumed that there are 6 stadia in a kilometer (km), meaning that Eratosthenes found the Earth's circumference to be about 42,000 km
5x - 2y = 10
Isolating y:
-2y = 10 - 5x
y = (10 - 5x)/(-2)
y = 10/(-2) + (-5x)/(-2)
y = -5 + 5/2x
This equation has the slope-intercept form with a slope of 5/2 and a y-intercept of -5
Answer:
3 parts cinnamon.
Step-by-step explanation:
Let's use a ratio:
cinnamon : sugar
1 : 3
3 : 9
We would need 3 parts sugar for this recipe.
