Subtract-a^2-5ab+3ab^2 from 3a^2-2ab+3b2
sergejj [24]

The correct answer is 4a^2 + 3ab

In order to find this, we can write the equation out as described and then follow the order of operations.

3a^2 - 2ab + 3b^2 - (-a^2 - 5ab + 3b^2) ----> Distribute the negative

3a^2 - 2ab + 3b^2 + a^2 + 5ab - 3b^2 ----> Combine like terms

4a^2 + 3ab

Haynes High School chartered buses for 60 students to go on a field trip. Valley High School chartered buses for 80 students.
Svetradugi [14.3K]

Answer: $20

Step-by-step explanation:

Let 'x' be the cost of a ticket at Haynes

Let 'y' be the cost of a ticket at Valley

Since the total cost from both schools are the same, we can write it as:

60x=80y

Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:

y=x-5

Now we have two equations, we can use to substitute into the other expression:

60x=80y

60x=80(x-5) we substitute y in this equation with the other equation

60x=80x-400

-20x =-400

x = 20

Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.
