Answer:
Step-by-step explanation:
Is 1.450 correct? 145 would make more sense. I'd even go with 1,450, just for a laugh. I'll assume 1.450 is the correct number here. I'll assume assute the question eventually asks how old are A and B.
A = 49(B)
A+B=1.450
Substitute:
49B+B=1.450
50B = 1.450
B = 0.029
A = 49*(0.029)
A = 1.421
2/3 = 0.6666666...... (I dont know how to put a bar above the 6)
3/11 = 0.27 (with a bar above the 27
8.4 (with a bar above the 4)
part A 17/23
part B 31/40
part C 23/40
part D Yes, sorry you gotta figure that out. Im to lazy to write a sentence
