3mn/-2p when m = 1/3, n = -3 , and p=3
To find the value of the expression 3mn/-2p when m = 1/3, n = -3, and p = 3, we substitute the given values into the expression:
3mn/-2p = 3(1/3)(-3)/(-2)(3) = (1)(-3)/(-2)(3) = -3/-6 = 1/2.
So, when m = 1/3, n = -3, and p = 3, the value of the expression 3mn/-2p is 1/2.
Which expression is equivalent to
(3xy-2xz+yz)+(2xy-4xz-5zy)
To simplify the expression (3xy-2xz+yz)+(2xy-4xz-5zy), we combine like terms:
First, let's group the terms:
(3xy + 2xy) + (-2xz - 4xz) + (yz - 5zy)
Next, let's combine the like terms within each grouping:
5xy + (-6xz) + (-4zy)
Finally, we can rearrange the terms:
5xy - 6xz - 4zy
Therefore, the expression (3xy-2xz+yz)+(2xy-4xz-5zy) is equivalent to 5xy - 6xz - 4zy.
Which expression is equivalent to
5x^2+3x-2x^2+4x
To simplify the expression 5x^2 + 3x - 2x^2 + 4x, we combine like terms:
First, let's group the terms:
(5x^2 - 2x^2) + (3x + 4x)
Next, let's combine the like terms within each grouping:
3x^2 + 7x
Therefore, the expression 5x^2 + 3x - 2x^2 + 4x is equivalent to 3x^2 + 7x.
which expression is equivalent to
-3(2x+5)+7
To simplify the expression -3(2x + 5) + 7, we will use the distributive property:
First, distribute -3 to each term inside the parentheses:
-3 * 2x + -3 * 5 + 7
This simplifies to:
-6x - 15 + 7
Next, combine like terms:
-6x - 8
Therefore, the expression -3(2x + 5) + 7 is equivalent to -6x - 8.
A state park charges an entrance fee plus $15 for each night of camping. The table shows this relationship. Which algebraic expression describes the total cost for camping `n` nights?
Sorry, but I cannot see the table you mentioned. Could you please provide the table or the specific values for the entrance fee and the cost per night of camping, so that I can help you determine the algebraic expression that describes the total cost for camping `n` nights?
To find the value of the expression 3mn/-2p when m = 1/3, n = -3, and p = 3, we substitute these values into the expression and simplify:
3(1/3)(-3)/(-2)(3)
First, we simplify the numerator:
3 * 1/3 = 1
So the numerator becomes:
1 * (-3) = -3
Now, we simplify the denominator:
-2 * 3 = -6
Finally, we divide the numerator by the denominator:
-3 / -6 = 1/2
Therefore, when m = 1/3, n = -3, and p = 3, the expression 3mn/-2p is equal to 1/2.
