Answer:
b
Step-by-step explanation:
Given
12x+ 8 = 10x + 18 ( subtract 10x from both sides )
2x + 8 = 18 ( subtract 8 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
The equation has one solution
Answer:
D. 10.1 centimeters
Step-by-step explanation:
Divide length by 10
The equation is provided below:
x = cost of DVD player
3x = cost of the movies
$532 = total amount purchased for the DVD player and the movies
$532 = x + 3x
$532 = 4x
$532 / 4 = 4x / 4
$133 = x (cost of the DVD player)
$133 * 3 = $399 (cost of the movies)
To check if the equation is correct:
$532 = $133 + ( 3 * $133)
$532 = $133 + $399
$532 = $532
The correct answer for the cost of the movies will be $399.

Answer:
1 9/16
Step-by-step explanation:
f(x)=x^2+2x+1
Let x = 1/4
f(1/4)=(1/4)^2+2*1/4+1
= 1/16+ 1/2 +1
= 1/16 + 8/16 + 1
=1 9/16
