Well the word “sum” means to add.
Other than that good luck.
Answer:6.1
Step-by-step explanation: the equation is 6n=30.5+n. the first thing you you do is subtract n on both sides which would be 6n-n which gives you 5. the equation now is 5n=30.5. now what you do is divide 5 on both sides so it would be 30.5/5 and that gives you 6.1
Answer:
See below.
Step-by-step explanation:
So, Nikki earns $12 per hour.
And she also earns a 5% or 0.05 commission of her total sales each day.
On Saturday, she worked eight hours and she earned $139. In other words, she earned 8(12) or $96 from working her hours and another $43 (139-96) from her commission.
Thus:

Where x represents Nikki's total sales on Saturday.
Further notes:
To solve, subtract 96 from both sides and divide by 0.05:

Thus, her total sales that day were $860.
Answer:
137°
Explanation:
In any triangle, the measure of the exterior angle is equal to the summation of the measures of the other two non-adjacent angles.
In the given triangle:
Angle 1 is an exterior angle.
The measures of the non-adjacent angles are 103° and 34°
Based on the above theorem:
measure angle 1 = 103 + 34 = 137°
Hope this helps :)
