Answer 1
She should put 7 students in each group. And there will be 4 groups.
Answer 2
She should put 4 students in each group and there will be 7 groups.
Explanation: 7*4 =28
Center piece was $40
Glasses were $2
I used the elimination method. I multiplied everything in the equation that represents the second order by five and subtracted it from the first orders equation. I then solved for y and got that each glass was $2. I then plugged the 2 back into the original equation to find that a centerpiece was $40.

Answer:
The answer to your question is z = 87 cm
Step-by-step explanation:
Data
Surface area of the rectangular prism = 8,462 cm²
Find z
Process
1.- Write and equation that help to solve the problem
Surface area = 2(13z) + 2(13)(31) + 2(31z)
-Simplify
8462 = 26z + 806 + 62z
8462 - 806 = 26z + 62z
7656 = 88z
z = 7656/88
-Result
z = 87 cm
