First distribute 6 into the parenthesis so that would be (6n - 18) - 2n = 10. Then erase the parenthesis to make the subtraction easier. So that would be 6n-18-2n=10. Then solve the subtraction by separating the unknown numbers with n and the normal numbers. So 6n-2n=4n 4n-18=10. To find n, add 18 and 10 to make both sides of the equation equal. So that would make 4n=28. Therefore n would be 7 because 28 divided by 4 makes 7.
Answer:
I believe the correct answer from the choices listed in the image is the second option. The statement that allows us to conclude that line m and line n are parallel would be that angle 2 and angle 7 are equal. They are alternate exterior angles. Hope this answers the question.
Answer: 2b+3
Combine like terms which are 5 and -2
So you have to divided 84 divided by 3 to figure out how much kids in each class. when you divide you get 28. So 28 kids in each room.....hope I helped.
