Since x represents the number of students, and y represents the number of adult chaperones (and x does not include y), the best answer is A, that there are x = 50 students on the field trip, and they are accompanied by y = 5 chaperones.
Note the difference with choice c, which says that 50 is the total (45 students, 5 adults).
Hi!
See my image for the answer.
I put each of the choices into the equation, then solved it.
The answer is B. (4,-12)
Hope this helps! :)

3/24 would be down to 1/8 so 3/24 is smaller
Answer:
B
Step-by-step explanation:
L = 3x + 2
W = 2x - 3
Area = L * W
Area = (3x + 2)(2x - 3) Use FOIL to expand.
F (First): 3x * 2x = 6x^2
O (Outside): (3x)( - 3) = - 9x
I (Inside): 2 * 2x = 4x
L (Last): 2*(-3) = - 6
Answer = F + O + I + L
Answer = 6x^2 - 9x + 4x - 6 Reduce
Answer = 6x^2 - 5x - 6
Answer: B
The answer to this question would be: <span>D) square inches</span>
In this question, Alex needs to find the surface area of a shoe box. Surface area unit would be represented by "square" because it is 2 dimension. The unit "cubic" is used for volume which was 3 dimension. From here, the option A and C is out because it uses cubic.
The inch unit is better since it was smaller than feet. If you using feet square, the area of the shoe box will be small and it might be less accurate than using inch.
