Paula's dog : Carolos' dog = 3 : 1
The total number of ratio units is 3+1 = 4, so each one stands for (48 lb)/4 = 12 lb.
Paula's dog weighs 3·12 lb = 36 lb.
Carlos' dog weighs 1·12 lb = 12 lb.
Answer:
The 2nd number in the sequence is 
Step-by-step explanation:
Let the six even numbers be 2x,2x+2,2x+4,2x+6,2x+8,2x+10
We are given that The sum of 6 even integers is 130.
So,2x+2x+2+2x+4+2x+6+2x+8+2x+10=130
12x+30=130
12x=100
So,the 2nd number in the sequence is

Answer:
x = -1 ± √3
Step-by-step explanation:
3x² − 2x − 1 = x² − 6x + 3
Move everything to one side.
2x² + 4x − 4 = 0
Divide by 2.
x² + 2x − 2 = 0
Solve with quadratic formula, or by completing the square.
x² + 2x = 2
x² + 2x + 1 = 3
(x + 1)² = 3
x + 1 = ±√3
x = -1 ± √3
