Answer:
What's the question?
Step-by-step explanation:
Responder:
Copias del libro A = 50
Copias del libro B = 70
Explicación paso a paso:
Costo por libros A = 200
Costo por libro B = 150
Sea el número de libros A = x
Número de libros B = y
Número total de libros comprados = 120
Costo total = 20,500
x + y = 120 - - - (1)
200x + 150y = 20500 - - - (2)
De 1)
x = 120 - y
Sustituya x = 120-y en (2)
200 (120 - años) + 150y = 20500
24000 - 200y + 150y = 20500
24000 - 50y = 20500
-50 años = 20500 - 24000
-50y = - 3500
y = 70
x = 120 - y
x = 120 - 70
x = 50
Answer:
2/10
Step-by-step explanation:
If you are trying to find out the probability of a number just know that the whole number is always going to be the denominator. In this problem, the denominator is <em>10</em> because that is the whole number of pieces of paper.
Then we look at the second part of the problem where it is asking us to figure out the probability of pulling out a number that is less than 3 which would only leave us with <em>1-2 </em>
This means that the probabilaty of pulling out a number less than 3 is <u><em>2/10</em></u>
Given:
The graph of an inequality.
To find:
The inequality.
Solution:
In the given graph, the boundary line passes through the points (-3,3) and (0,1).
So, the equation of the boundary line is:
Adding 3 on both sides, we get
The boundary line is a solid line and the shaded region is above the boundary line. So, the sign of inequality must be 
and the required inequality is:
Therefore, the correct option is B.
The answer is 60. The formula is v=bxhxh/b or in this case 6x4x15/6. After you multiply the numerator you will get 360 and then you divide by 6 to get your answer: 60.
