Answer:
w=66
Step-by-step explanation:
w-19=47
Hey There!
So what we want to do is get the variable on one side (w) and the constant on the other
so essentially what I am saying is that we have to get rid of the -19 and to do that we have to add 19
but remember whatever we do to one side we have to do to the other
-19+19 cancels out
47+19=66
therefore
w=66
Answer:
<h2>3500 is the correct answer .</h2>
Step-by-step explanation:
<h3> ( 7×10^5) ÷ (2×10^2)</h3><h3 /><h3>= (7 × 100000) ÷ ( 2×100)</h3><h3 /><h3>= 700000 ÷ 200</h3>
<h3>= 3500 </h3>

Answer:
(7, 0), (-8, 0), (0, 0)
Step-by-step explanation:
y = f(x) = 0
the real solutions are the ones that cross the x-axis because when a point is on the x-axis, its y coordinate will be 0.
=> (7, 0), (-8, 0), (0, 0)
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
