Answer:
{
}
Step-by-step explanation:
The given system of equations is;
and
We rewrite the equations in the standard form to get:
We now substitute equation (3) into equation (4) to get:
Group similar terms:
Divide both sides by 2
This implies that:
Therefore the solution set is:
{}
Answer:
15 kg, 22.5 kg, 52.5 kg
Step-by-step explanation:
Let the common multiplier of the given ratios be x. Therefore, weights of each bag would be 2x, 3x and 7x
According to the given information:
Hence the weight of sand in bag would be 15 kg, 22.5 kg and 52.5 kg
C is correct because the first point is on 0
V= a^3
So in this case V= 6^3
V= 216
