Answer:
$110
Step-by-step explanation:
Let a, b, and c represent the earnings of Alan, Bob, and Charles. The problem statement tells us ...
a + b + c = 480 . . . . . . the combined total of their earnings
-a + b = 40 . . . . . . . . . . Bob earned 40 more than Alan
2a - c = 0 . . . . . . . . . . . Charles earned twice as much as Alan
Adding the first and third equations, we get ...
(a + b + c) + (2a - c) = (480) + (0)
3a + b = 480
Subtracting the second equation gives ...
(3a +b) - (-a +b) = (480) -(40)
4a = 440 . . . . . . . . simplify
a = 110 . . . . . . . . . . divide by the coefficient of a
Alan earned $110.
_____
<em>Check</em>
Bob earned $40 more, so $150. Charles earned twice as much, so $220.
The total is then $110 +150 +220 = $480 . . . . as required
Answer:
Step-by-step explanation:
Solving for the variable 
, given that :
We can first start start by subtracting 
from both sides of the equation:
Now, we can divide both sides of the equation by the coefficient of , which would be 
:
Applying the fraction rule 
:
Then, apply the fraction rule 
Answer:
The total angle (Angle FGH) = 141 degrees
Angle 1 = 59 degrees
To find this, all you need to do is subtract 59 degrees from 141 degrees.
Because Angle 1 and Angle 2 make up Angle FGH, which - 141 degrees.
141 degrees is your (considered) total amount of degrees, and 59 degrees is apart of it. So, 141 - 59 = 82 degrees.
Angle 2 = 82 degrees.
I hope this helps!

Answer:
35 students
Step-by-step explanation:
Take the number of students in the class and multiply by 60% and see if you get an integer number
28 * .60 =16.8 not an integer
32 * .6 =19.2
35 * .6 =21 yes
39*.6 =23.4
