Anne
Step-by-step explanation:
The expression cannot be simplified anymore, but it can be laid out correctly.
The greatest number for the exponents should come first, so Anne is the one who laid it out correctly.
Hope it helps!!

Answer:
75
Step-by-step explanation:
Given data
First term= 87
Second term= -12
Hence,
87 + (-12)
open bracket
+*-= -
= 87 -12
=75
Therefore the equivalent is 75
Answer: Tahat= 40.5 marks Promi =29.5 marks, Kabi =24.5 marks
Step-by-step explanation:
Step 1
Let the marks be represented as x+11, x and x-5 for Tahat, Promi and Kabi respectively
and Tahat's marks which was 75% of the sum of Promi and Kabi's marks be expressed as
x+11 = 75/100(x + x-5)
Step 2 --- Solving
x+11 = 75/100(x + x-5)
x+ 11 = 3/4(2x-5)
x+11= 6x-15/4
4x+44=6x-15
44+15=2x
x= 59/2= 29.5,
A) x= Promi's mark was 29.5
B)Promi secured 5 marks more than kabi
Therefore, Kabi's mark was 5 marks less than Promi
= x-5
29.5- 5= 24.5 marks
C)Promi secured 11 marks less than Tahat, Therefore Tahat marks were 11 marks more than Promi
x+11= 29.5 + 11= 40.5
