11) a - 15 >-40-6 + 3a)​

Mathematics
1 answer:
SOVA2 [1]2 years ago
4 0

Answer:

a < \frac{31}{2}

Step-by-step explanation:

Given

a - 15 > - 40 - 6 + 3a ← simplify right side

a - 15 > - 46 + 3a ( subtract a from both sides )

- 15 > - 46 + 2a ( add 46 to both sides )

31 > 2a ( divide both sides by 2 )

\frac{31}{2} > a ⇒ a < \frac{31}{2}

Round 69581.491337 to the nearest thousand.
Anika [276]

Answer:

7000

Step-by-step explanation:

lets start with 695

9 is the thousand

you check the number next to 9

less then 4 let it rest

more than 5 let it soar

something like that lol

anyways since 5 is next to the 9 we round up from 9 to the next number which is 10

so that changes the whole number to 7000

hope this makes sense!
