Answer:
Step-by-step explanation:
What we know is that A + S = 111. That is, the miles Andre drove plus the miles Scott drove totalled 111 miles. What we also know is that Scott drove quite a bit more than Andre did. Scott drove 7 miles more that ( +7 ) 3 times the number of miles Andrea drove. That looks like this algebraically:
S = 3A + 7
Now we can sub in that value for S to the original equation:
If A + S = 111 and S = 3A + 7, then
A + 3A + 7 = 111 and
4A + 7 = 111 and
4A = 104 so
A = 26 and
S = 3(26) + 7 so
S = 85 miles.
Scott drove 85 miles.
6.4 pints a minuet. this is the answer because 8 gallons is 64 pints, there are 60 minuets in an hour so 64/60 is 6.4 pints.
2/10 simply means 2 divided by 10 = 0.2
Answer:
About 3.11
Step-by-step explanation:
Add the numbers and divide the value by the number of values in the data set.
6 + 3 + 5 + 2 + 2 + 3 + 3 + 1 + 3 = 28
28/9 = 3.1111...
3.111... ≈ 3.11
Hope this helps.
