Answer:
Hey there!
5(v+3)-10v>-10
5v+15-10v>-10
-5v+15>-10
-5v>-25
v<5
Let me know if this helps :)
Step-by-step explanation:
5(v + 3) - 10v > -10
Expand brackets.
5v + 15 - 10v > -10
Combine like terms.
-5v + 15 > -10
Subtract 15 from both parts.
-5v > -25
Divide both parts by -5 (flip sign).
v < 5
3.16227766017
rounded it is 3
Yes because it fits the Pythagorean Theorem
see: 5 ^2 = 25
and 3^2 + 4^2 = 9 + 16 = 25
25 = 25
so it is
40 meters and 2 times
