Answer:
idk sruy
Step-by-step explanation:
The answer is 5. good luck!
2 hours, the extra 30 miles last month indicates that every 30 miles totals 1 hour so if she traveled 60 miles then she traveled for 2 hours
<span>3x+5y=2 (1)
9x+11y=14 (2)
multiply equation (1) by 3
9x + 15y = 6
so
</span>9x + 15y = 6 (1')
9x + 11y =14 (2)
-------------------------subtract
4y = -8
y = -2
3x+5y =2
3x+5(-2) =2
3x - 10 = 2
3x = 12
x = 4
answer
(4, -2)
I'll try to help you round these numbers
37 rounded to Tens will be 40
because 7 is bigger than 3 so the 7 will change the 3 to a 4 and the 7 will be a 0.
29 rounded to Tens will be 30
because the 9 is bigger than 2 so it will change the 2 to a 3 and the 9 will be a 0. Just like 37 rounded into a 40.
669 rounded to Hundreds will be 700
Its 700 because the 9 is bigger and it will change the 6 beside it to a 10 which means that the 9 will be a 0. The 6 that turned to a 10 will turned will be a 0 because your carry the 1 to the other 6 which would turn to a 7 and the two numbers behind 7 will be 0's which makes that be 700.
9,492 rounded to Thousands will be 9,000
Ok this is 9,000 because the 4 is smaller than 9 which the 9 will become the bigger person and turn all the little numbers thats behind it to 0's and even that 9 between the 4 and the 2. So thats why its 9,000.
Hope this helps!
