Step 1: -9+n=-18. You would add the inverse to both sides, meaning you’d add nine to the negative nine to cancel it out and then then 9 to -18.
-9+n=-18
+9 +9
That would leave you with the equation: n=-9, since -18 plus a positive 9 equals a negative nine. You’re final answer is n= -9.
You can check you answer by substituting the variable with the solution (-9).
-9 + -9= -18

Answer:
He got an 80 percent.
Step-by-step explanation:
The most used fractions on a number line used before 1 are 1/4, 1/2, 1/3, 2/4, 2/3, and 3/4.
Pi radians =180 degrees:
<span>That is, π rad = 180°
</span>
60° in radian measure = 60° × π / 180°
60° × π / 180° = 1/3 π rad
= 0.33333333333π rad
=
1.0471975512 rad
