33.75 i think
Multiply 9 by 3 you get 27
Divide 9 by 4 and get 2.25
Multiply 2.25 by 3 which is 6.75
Add 27 and 6.75
33.75
Answer:
vertices (V) = 6, faces (F) = 12 and edges (E) = 16
Step-by-step explanation:
A polyhedron is a three-dimensional shape with straight edges and flat faces and sharp corners.The point where the faces of a polyhedron meet each other is known as the edge while the corners of the polyhedron is known as the vertices.
Euler formula gives the relationship between the number of vertices (V), faces (F) and edges (E) of a polyhedron. This formula is given as:
F + V - E = 2.
Given that:
E - V = 10, Therefore E = V + 10
F = 2 × V = 2V
Substituting into the Euler formula:
2V + V - (V + 10) = 2
2V + V - 10 - V = 2
2V = 12
V = 12/2 = 6
Therefore, E = V + 10 = 6 + 10 = 16
F = 2V = 2 × 6 = 12
Step-by-step explanation:
Let the number is x. Its reciprocal will be 1/x. According to given condition, we get :
It is a quadratic equation. The values of x are :
The smaller number is 4/5 and the larger number is 5/4.
The answer to your question would be: Because 4 + (-7) is an equivalent expression, your answer is -3. The reason for this can be described using integers. So lets say you have $4. You owe your brother $7. Since you don't have enough to pay him, you can pay him all your money, but you still have to pay him $3 more. This means technically your balance is $-3, cause if he needs the money, the second you get it he will ask for it. Sorry if this isn't too great of an example, not sure what else I could think of. Pretty much remember when subtracting a number, you can add the negative of the number, because that is the same thing. Hope this helps.
