184.2 is the answer to 4 significant figure
Step-by-step explanation:
4 balls = 344
7 balls = 7×344/4= 602
Y=-3x+36 because the line crosses the y axis at 36
You do the sum(40) subtracted by 8, the answer from that divided by 2 since Erin's two times younger.
40-8=32
32÷2=16
Then if you want to check it you do the opposite and get the same sum(40) so 16×2=32 and 32+8=40
The answer is D 16a: 1,2,3,4,8,16 and 18ab:1,2,3,46,9,18 a,b
