<span>Let the first number be x.
Then the second number is 3x.
Then the third number is (x+100).
Sum of the numbers=500
x+3x+(x+100)=500</span>
<span>4x+(x+100)-500=0
</span><span>5x=400</span>
<span>x=80
</span><span>The first number is 80.
The second number is 240.
The third number is 180.
We can check by adding all three of those numbers together: 80+240+180 = 500

Answer:
a = - 5, a = - 3
Step-by-step explanation:
Given
a² + 8a + 15 = 0 ← in standard form
(a + 3)(a + 5) = 0 ← in factored form
Equate each factor to zero and solve for a
a + 3 = 0 ⇒ a = - 3
a + 5 = 0 ⇒ a = - 5

Step-by-step explanation:
15.25 for blueberry pie = 24 slices (8 slices in a pie)
12.84 for cherry pie = 15 slices (8 slices in a pie)
24x3.50=84
15x3.50=52.5
2x12.84=25.68
3x15.25=45.75
84-45.75=34.25
52.5-25.68=26.82
