Answer:
x = 3
Step-by-step explanation:
4x+2 = x+11
Subtract x from each side
4x+2-x = x+11-x
3x+2 =11
Subtract 2 from each side
3x+2-2 =11-2
3x = 9
Divide by 3
3x/3 =9/3
x = 3
Answer:
In a year, $105
In a decade, $150
In a century, $600
In a milleniun, $5100
Step-by-step explanation:
The formula is very simple: Multiply by 5 each year, and then you add it to the $100
6--3=9
15-6=9,
so
24+9=33,
33+9=42,
42+9=51
33,42,51

Answer:
2 1/12 days
Step-by-step explanation:
Time is the ratio of distance to speed.
(1200 mi)/(24 mi/h) × (1 day)/(24 h) = 25/12 day = 2 1/12 days
Answer:
x ≈ - 9.41, x ≈ - 6.59
Step-by-step explanation:
Given
x² + 16x + 62 = 0 ( subtract 62 from both sides )
x² + 16x = - 62
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(8)x + 64 = - 62 + 64
(x + 8)² = 2 ( take the square root of both sides )
x + 8 = ±
( subtract 8 from both sides )
x = - 8 ± 
Hence
x = - 8 -
≈ - 9.41
x = - 8 +
≈ - 6.59
