Answer: b
Step-by-step explanation:
Let h = the number of horses in the field
Let c = number of cows in the field
There are 2 more horses than cows in the field. Therefore
h = c + 2
or
c = h - 2 (1)
There are 15 animals in the field. Therefore
h + c = 15 (2)
Substitute (1) into (2).
h + (h - 2) = 15
2h - 2 = 15
Answer:
The correct equation is
2h - 2 = 15
30% of the 30 marbles is nine and 9-30 = 21 so your answer is 21
Answer:c
Step-by-step explanation:I just did this one and got it correct
Answer: The correct option is D.
Explanation:
From the graph we noticed that the x intercept of the line is (2,0) and the y-intercept is (0,2).
If the line passing through two points then the equation of line is,

Since the ien passing through (2,0) and (0,2).



This equation is represented by option D, therefore the option D is correct.
