By definition of absolute value we have two equalities:
2x + 1 = 10
2x + 1 = -10
For 2x + 1 = 10:
2x + 1 = 10
2x = 10-1
2x = 9
x = 9/2
For 2x + 1 = -10:
2x + 1 = -10
2x = -10-1
2x = -11
x = -11 / 2
Answer:
{-11/2, 9/2}
Look at the picture.
Use the Pythagorean theorem:
Answer:
3w - 9/2 is the equivalent expression
Answer:
Equation: $1.67n=C
Step-by-step explanation:
n= pounds of apples
C= total price
$1.67 of apples per pound
Since we dont know the number of pounds of aplles we write n next to $1.67. And C as the total price for n punds of apples.
