45 + 15x <= 120
15x <= 75 Subtract 45 from both sides
x <= 5 less than or equal to 5 hours
S = 32200 + 700y
S stands for salary and y stands for year
<h3>
Answer: 21</h3>
==================================
Work Shown:
Vertical angles are always congruent.
This means they are equal in measure.
A = B
3x-30 = 2x-9
3x-2x = -9+30
x = 21
--------
Side note:
if x = 21, then,
A = 3*x-30 = 3*21-30 = 33 degrees
B = 2*x-9 = 2*21-9 = 33 degrees
By using the rule -b/2a —> 12/-6= -2
Answer:
20 30 40 40 50 60 70 80 90 100
