4 ducks (4 heads, 8 legs) and 2 sheep (2 heads, 8 legs). Altogether, 6 heads and 16 legs.
Answer:
The correct option is B.
Step-by-step explanation:
The given equation are


On solving both the equation, we get




Put this value in the given equation.




The solution of the given system of equation is

The best approximation of the exact solution is (1.3,2.3). Therefore the correct option is B.
The answer is C.
Note when Soro divides both sides by -2.5 to solve the equation. When multiplying/dividing by a negative number, one should always reverse the inequality sign, but Soro forgot to do this.
-2.5x≥-30
After this step, the answer SHOULD HAVE been:
x≤12
Let me know if you need any clarifications, thanks!
The area of square TUVW = 3×3 = 9 square units
1 square unit = 4 head lettuces
9 square units = 9×4 = 36 lettuces
Area of plot QRST = length × width = 12×6 = 72 square units
36 vegetables for every 9 square units
We have 72÷9 = 8 lots of 9 square units
Total vegetable = 8 × 36 = 288 vegetables
We can have 8 different vegetables, each type can have 36 vegetables
