Answer:
<h2>x = 20</h2>
Step-by-step explanation:
The angles 7x° and (x + 20)° are supplementary angles.
Supplementary angles add up to 180°.
Therefore we have the equation:
7x + (x + 20) = 180
7x + x + 20 = 180 <em>subtract 20 from both sides</em>
8x = 160 <em>divide both sides by 8</em>
x = 20
Answer:
36 passengers
Step-by-step explanation:
Maria averages 20 passengers every 20 minutes, so she places 1 passenger per minute.
Sal averages 20 passengers every 25 minutes, so he places 0.8 passenger per minute.
If they work together, they can place (1 + 0.8) passengers = 1.8 passengers per minute.
In 20 minutes, they can load
1.8 passengers/minute * 20 minutes = 36 passengers
Answer:
