Hey there! :)
-6 < -2x < 14
We're trying to solve for x. To solve for x, we must isolate x.
So, let's divide everything by -2!
-6 ÷ -2 < -2x ÷ -2 < 14 ÷ -2
**Remember : when dividing by a negative number, you MUST switch the sign! So, if the sign is ">" then we switch it to "<" and the other way around **
3 > x > -7
So, our answer is : → 3 > x > -7
~Hope I helped!~
Let n represent the number.
1/3n = n - 12
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
Simply divide the minutes by laps.
38 / 8 = 4.75
Hannah runs 1 lap in 4.75, or 4 3/4 minutes.
