Answer:
A) a • (b • c) = (a • b) • c
Step-by-step explanation:
The associative property of multiplication (or addition) shows that the order the numbers are multiplied it irrelevant, more specifically in the manners of parentheses.
So, the answer is A, which can also be seen in that substituting a as 5, b as 3, and c as 6 gives us the first example.
Answer:
t ≥ 18
Step-by-step explanation:
He has run 12 miles plus some more miles t. He need to run at least 30 miles

t ≥ 18

i dont know B sorry
Step-by-step explanation:
42 is the answer
Explanation:
50% of 80 is half of 80 which is 40
Then you would add 40 with 5% of 40
What you would do then is 5% times 40 then you would change the 5% into a decimal which is 0.05 and multiply it by 40 , which would get u 2
Then you would add the price with tax
40+2 = 42
Anything between the decimal and last non-zero digit
so 00025 are significant
the 0 in front is insignificant because it could be
00000.00025
zeroes after the 25 don't matter becasue it could be
0.000250000000 and it wouldn't change
the sig figs are 00025
