The expression 3xy+2xz+yz + 2xy−4xz+5yz can be simplified by combining like terms.
Combining the terms that have "xy," we get 3xy + 2xy = 5xy.
Combining the terms that have "xz," we get 2xz - 4xz = -2xz.
Combining the terms that have "yz," we get yz + 5yz = 6yz.
Therefore, the simplified expression is 5xy - 2xz + 6yz.
The correct answer is 5xy - 2xz + 6yz.
Combining the terms that have "xy," we get 3xy + 2xy = 5xy.
Combining the terms that have "xz," we get 2xz - 4xz = -2xz.
Combining the terms that have "yz," we get yz + 5yz = 6yz.
Therefore, the simplified expression is 5xy - 2xz + 6yz.
The correct answer is 5xy - 2xz + 6yz.

The total cost for a single order of x cartridges can be found by adding the cost of the cartridges and the flat rate charged by the company.
The cost of the cartridges is $26 per cartridge, and the flat rate charge is $6.50.
Therefore, the algebraic expression that describes the total cost for a single order of x cartridges is:
Total cost = (26 * x) + 6.50
The cost of the cartridges is $26 per cartridge, and the flat rate charge is $6.50.
Therefore, the algebraic expression that describes the total cost for a single order of x cartridges is:
Total cost = (26 * x) + 6.50

To evaluate the expression 3b - ac when a = 2, b = 3, and c = -1.5, we substitute the given values into the expression and perform the calculations.
3b = 3(3) = 9
ac = 2(-1.5) = -3
Substituting these values into the expression, we get:
3b - ac = 9 - (-3) = 9 + 3 = 12
Therefore, the value of the expression 3b - ac is 12.
3b = 3(3) = 9
ac = 2(-1.5) = -3
Substituting these values into the expression, we get:
3b - ac = 9 - (-3) = 9 + 3 = 12
Therefore, the value of the expression 3b - ac is 12.
