Answer:
The variables are A and B. A for Andy, and B for Brett. B=18, and A=26
Step-by-step explanation:
A+B=44
A=B+8
B + 8 + B = 44
2B+8=44
2B = 36
B = 18
A = 26
The temp. started at -20. If it rose +8 degrees, then it would be -20+8=-12, because since the -20 and +8 are opposites, you would subtract them and the answer would have the sign of the larger number which is -. so -12 is the answer.
