Answer:
a.) To find the range, you subtract the biggest number from the smallest and you will get the range.
b.) 12.3 - 17.5 = 5.2
Step-by-step explanation:
x = -12
y = x/2 + 9
y = -12/2 + 9
y = -6 + 9
y = 3
4 x 10^8 metres.
[0.0001 x (4 x 10^12)
= 4 x 10 ^8
the answer is 49
I may not be correct
1/12
1/4+2/3=11/12
