Answer:
$2 per Chicken and $9 per Duck
Step-by-step explanation:
the equations for the problem are as follows (x = the value of chickens and y = the value of ducks):
5x + 3y = 55
4x + 3y = 53
if you subtract the equations you would get x = 2, which means the chickens are worth $2 each
If we re-input the x that we now know as 2 and solve one of the equations for y, we will get y = 9
The answer is b for your question

Answer:
200 stones.
Step-by-step explanation:
Given that the verandah is 40 meters long by 15 meters wide, and that it is going to be paved with stones that measure 6 decimeters by 5 decimeters, to determine the amount of stones that should be used, the following calculation must be performed:
1 m = 10 dm
Verandah's surface: 40 x 15 = 600m2
Stones' surface: 6 x 5 = 30dm2 = 3m2
600/3 = X
200 = X
Therefore, 200 stones should be used to pave the entire verandah.
